Kabbalah

Kabbalah or Qabalah (/kəˈbɑːlə, ˈkæbələ/ kə-BAH-lə, KAB-ə-lə; Hebrew: קַבָּלָה‎, romanized: Qabbālā, lit. 'reception, tradition')^[1][a] is an esoteric method, discipline and school of thought in Jewish mysticism.^[2] A traditional Kabbalist is called a Mekubbal (מְקוּבָּל‎, Məqūbbāl, 'receiver').^[2] The definition of Kabbalah varies according to the tradition and aims of those following it.^[3] According to its earliest and original usage in ancient Hebrew it means 'reception' or 'tradition', and in this context it tends to refer to any sacred writing composed after (or otherwise outside of) the five books of the Torah.^[4] After the Talmud is written, it refers to the Oral Law (both in the sense of the 'Talmud' itself and in the sense of continuing dialog and thought devoted to the scripture in every generation).^[4] In the much later writings of Eleazar of Worms (c. 1350), it refers to theurgy or the conjuring of demons and angels by the invocation of their secret names.^[4] The understanding of the word Kabbalah undergoes a transformation of its meaning in medieval Judaism, in the books which are now primarily referred to as 'the Kabbalah': the Bahir, the Zohar, Etz Hayim etc.^[4] In these books the word Kabbalah is used in manifold new senses. During this major phase it refers to the continuity of revelation in every generation, on the one hand, while also suggesting the necessity of revelation to remain concealed and secret or esoteric in every period by formal requirements native to sacred truth.^[4] When the term Kabbalah is used to refer to a canon of secret mystical books by medieval Jews, these aforementioned books and other works in their constellation are the books and the literary sensibility to which the term refers.^[4] Even later the word is adapted or appropriated in Western esotericism (Christian Kabbalah and Hermetic Qabalah), where it influences the tenor and aesthetics of European occultism practiced by gentiles or non-Jews. But above all, Jewish Kabbalah is a set of sacred and magical teachings meant to explain the relationship between the unchanging, eternal God—the mysterious Ein Sof (אֵין סוֹף‎, 'The Infinite')^[5][6]—and the mortal, finite universe (God's creation).^[2][5] It forms the foundation of mystical religious interpretations within Judaism.^[2][7]

Jewish Kabbalists originally developed their own transmission of sacred texts within the realm of Jewish tradition^[2][7] and often use classical Jewish scriptures to explain and demonstrate its mystical teachings. These teachings are held by Kabbalists to define the inner meaning of both the Hebrew Bible and traditional rabbinic literature and their formerly concealed transmitted dimension, as well as to explain the significance of Jewish religious observances.^[8]

Historically, Kabbalah emerged from earlier forms of Jewish mysticism, in 12th- to 13th-century Spain and Southern France,^[2][7] and was reinterpreted during the Jewish mystical renaissance in 16th-century Ottoman Palestine.^[2] The Zohar, the foundational text of Kabbalah, was composed in the late 13th century. Isaac Luria (16th century) is considered the father of contemporary Kabbalah; Lurianic Kabbalah was popularised in the form of Hasidic Judaism from the 18th century onwards.^[2] During the 20th century, academic interest in Kabbalistic texts led primarily by the Jewish historian Gershom Scholem has inspired the development of historical research on Kabbalah in the field of Judaic studies.^[9][10]

Though innumerable glosses, marginalia, commentaries, precedent works, satellite texts and other minor works contribute to an understanding of the Kabbalah as an evolving tradition, the major texts in the main line of Jewish mysticism that inarguably fall under the heading 'Kabbalah'—conforming to the sense of every definition and meeting all of the various diagnostic criteria of these different perspectives—are the Bahir, Zohar, Pardes Rimonim, and Etz Chayim ('Ein Sof').^[11] The early Hekhalot writings are acknowledged as ancestral to the sensibilities of this later flowering of the Kabbalah^[12] and more especially the Sefer Yetzirah is acknowledged as the antecedent from which all these books draw many of their formal inspirations. The Sefer Yetzirah is a brief document of only few pages that was written many centuries before the high and late medieval works (sometime between 200-600CE), detailing an alphanumeric vision of cosmology—may be understood as a kind of prelude to the canon of Kabbalah.^[11]

The history of Jewish mysticism encompasses various forms of esoteric and spiritual practices aimed at understanding the divine and the hidden aspects of existence. This mystical tradition has evolved significantly over millennia, influencing and being influenced by different historical, cultural, and religious contexts. Among the most prominent forms of Jewish mysticism is Kabbalah, which emerged in the 12th century and has since become a central component of Jewish mystical thought. Other notable early forms include prophetic and apocalyptic mysticism, which are evident in biblical and post-biblical texts.

The roots of Jewish mysticism can be traced back to the biblical era, with prophetic figures such as Elijah and Ezekiel experiencing divine visions and encounters. This tradition continued into the apocalyptic period, where texts like 1 Enoch and the Book of Daniel introduced complex angelology and eschatological themes. The Heikhalot and Merkavah literature, dating from the 2nd century to the early medieval period, further developed these mystical themes, focusing on visionary ascents to the heavenly palaces and the divine chariot.

The medieval period saw the formalization of Kabbalah, particularly in Southern France and Spain. Foundational texts such as the Bahir and the Zohar were composed during this time, laying the groundwork for later developments. The Kabbalistic teachings of this era delved deeply into the nature of the divine, the structure of the universe, and the process of creation. Notable Kabbalists like Moses de León played crucial roles in disseminating these teachings, which were characterized by their profound symbolic and allegorical interpretations of the Torah.

In the early modern period, Lurianic Kabbalah, founded by Isaac Luria in the 16th century, introduced new metaphysical concepts such as Tzimtzum (divine contraction) and Tikkun (cosmic repair), which have had a lasting impact on Jewish thought. The 18th century saw the rise of Hasidism, a movement that integrated Kabbalistic ideas into a popular, revivalist context, emphasizing personal mystical experience and the presence of the divine in everyday life. Today, the academic study of Jewish mysticism, pioneered by scholars like Gershom Scholem, continues to explore its historical, textual, and philosophical dimensions.

According to the Zohar, a foundational text for kabbalistic thought,^[13] Torah study can proceed along four levels of interpretation (exegesis).^[14][15] These four levels are called pardes from their initial letters (PRDS פַּרדֵס‎, 'orchard'):

• Peshat (Hebrew: פשט lit. 'simple'): the direct interpretations of meaning.^[16]
• Remez (רֶמֶז‎ lit. 'hint[s]'): the allegoric meanings (through allusion).
• Derash (דְרָשׁ‎ from the Hebrew darash: 'inquire' or 'seek'): midrashic (rabbinic) meanings, often with imaginative comparisons with similar words or verses.
• Sod (סוֹד, lit. 'secret' or 'mystery'): the inner, esoteric (metaphysical) meanings, expressed in kabbalah.

Kabbalah is considered by its followers as a necessary part of the study of Torah – the study of Torah (the Tanakh and rabbinic literature) being an inherent duty of observant Jews.^[17]

Modern academic-historical study of Jewish mysticism reserves the term kabbalah to designate the particular, distinctive doctrines that textually emerged fully expressed in the Middle Ages, as distinct from the earlier Merkabah mystical concepts and methods.^[18] According to this descriptive categorization, both versions of Kabbalistic theory, the medieval-Zoharic and the early-modern Lurianic Kabbalah together comprise the Theosophical tradition in Kabbalah, while the Meditative-Ecstatic Kabbalah incorporates a parallel inter-related Medieval tradition. A third tradition, related but more shunned, involves the magical aims of Practical Kabbalah. Moshe Idel, for example, writes that these 3 basic models can be discerned operating and competing throughout the whole history of Jewish mysticism, beyond the particular Kabbalistic background of the Middle Ages.^[19] They can be readily distinguished by their basic intent with respect to God:

• The Theosophical or Theosophical-Theurgic tradition of Theoretical Kabbalah (the main focus of the Zohar and Luria) seeks to understand and describe the divine realm using the imaginative and mythic symbols of human psychological experience. As an intuitive conceptual alternative to rationalist Jewish philosophy, particularly Maimonides' Aristotelianism, this speculation became the central stream of Kabbalah, and the usual reference of the term kabbalah. Its theosophy also implies the innate, centrally important theurgic influence of human conduct on redeeming or damaging the spiritual realms, as man is a divine microcosm, and the spiritual realms the divine macrocosm. The purpose of traditional theosophical kabbalah was to give the whole of normative Jewish religious practice this mystical metaphysical meaning.
• The Meditative tradition of Ecstatic Kabbalah (exemplified by Abraham Abulafia and Isaac of Acre) strives to achieve a mystical union with God, or nullification of the meditator in God's Active intellect. Abraham Abulafia's "Prophetic Kabbalah" was the supreme example of this, though marginal in Kabbalistic development, and his alternative to the program of theosophical Kabbalah. Abulafian meditation built upon the philosophy of Maimonides, whose following remained the rationalist threat to theosophical Kabbalists.^[20]
• The Magico-Talismanic tradition of Practical Kabbalah (in often unpublished manuscripts) endeavours to alter both the Divine realms and the World using practical methods. While theosophical interpretations of worship see its redemptive role as harmonising heavenly forces, Practical Kabbalah properly involved white-magical acts, and was censored by Kabbalists for only those completely pure of intent, as it relates to lower realms where purity and impurity are mixed. Consequently, it formed a separate minor tradition shunned from Kabbalah. Practical Kabbalah was prohibited by the Arizal until the Temple in Jerusalem is rebuilt and the required state of ritual purity is attainable.^[21]

According to Kabbalistic belief, early kabbalistic knowledge was transmitted orally by the Patriarchs, prophets, and sages, eventually to be "interwoven" into Jewish religious writings and culture.^[22] According to this view, early kabbalah was, in around the 10th century BCE, an open knowledge practiced by over a million people in ancient Israel.^[23][24] Foreign conquests drove the Jewish spiritual leadership of the time (the Sanhedrin) to hide the knowledge and make it secret, fearing that it might be misused if it fell into the wrong hands.^[25]

It is hard to clarify with any degree of certainty the exact concepts within kabbalah. There are several different schools of thought with very different outlooks; however, all are accepted as correct.^[26] Modern halakhic authorities have tried to narrow the scope and diversity within kabbalah, by restricting study to certain texts, notably Zohar and the teachings of Isaac Luria as passed down through Hayyim ben Joseph Vital.^[27] However, even this qualification does little to limit the scope of understanding and expression, as included in those works are commentaries on Abulafian writings, Sefer Yetzirah, Albotonian writings, and the Berit Menuhah,^[28] which is known to the kabbalistic elect and which, as described more recently by Gershom Scholem, combined ecstatic with theosophical mysticism. It is therefore important to bear in mind when discussing things such as the sephirot and their interactions that one is dealing with highly abstract concepts that at best can only be understood intuitively.^[29]

From the Renaissance onwards Jewish Kabbalah texts entered non-Jewish culture, where they were studied and translated by Christian Hebraists and Hermetic occultists.^[30] The syncretic traditions of Christian Cabala and Hermetic Qabalah developed independently of Judaic Kabbalah, reading the Jewish texts as universalist ancient wisdom preserved from the Gnostic traditions of antiquity. Both adapted the Jewish concepts freely from their Jewish understanding, to merge with multiple other theologies, religious traditions and magical associations. With the decline of Christian Cabala in the Age of Reason, Hermetic Qabalah continued as a central underground tradition in Western esotericism. Through these non-Jewish associations with magic, alchemy and divination, Kabbalah acquired some popular occult connotations forbidden within Judaism, where Jewish theurgic Practical Kabbalah was a minor, permitted tradition restricted for a few elite. Today, many publications on Kabbalah belong to the non-Jewish New Age and occult traditions of Cabala, rather than giving an accurate picture of Judaic Kabbalah.^[31] Instead, academic and traditional Jewish publications now translate and study Judaic Kabbalah for wide readership.

The nature of the divine prompted kabbalists to envision two aspects to God: (a) God in essence, absolutely transcendent, unknowable, limitless divine simplicity beyond revelation, and (b) God in manifestation, the revealed persona of God through which he creates and sustains and relates to humankind. Kabbalists speak of the first as Ein/Ayn Sof (אין סוף "the infinite/endless", literally "there is no end"). Of the impersonal Ein Sof nothing can be grasped. However, the second aspect of divine emanations, accessible to human perception, dynamically interacting throughout spiritual and physical existence, reveal the divine immanently, and are bound up in the life of man. Kabbalists believe that these two aspects are not contradictory but complement one another, emanations mystically revealing the concealed mystery from within the Godhead.

As a term describing the Infinite Godhead beyond Creation, Kabbalists viewed the Ein Sof itself as too sublime to be referred to directly in the Torah. It is not a Holy Name in Judaism, as no name could contain a revelation of the Ein Sof. Even terming it "No End" is an inadequate representation of its true nature, the description only bearing its designation in relation to Creation. However, the Torah does narrate God speaking in the first person, most memorably the first word of the Ten Commandments, a reference without any description or name to the simple Divine essence (termed also Atzmus Ein Sof – Essence of the Infinite) beyond even the duality of Infinitude/Finitude. In contrast, the term Ein Sof describes the Godhead as Infinite lifeforce first cause, continuously keeping all Creation in existence. The Zohar reads the first words of Genesis, BeReishit Bara Elohim – In the beginning God created, as "With (the level of) Reishit (Beginning) (the Ein Sof) created Elohim (God's manifestation in creation)":

At the very beginning the King made engravings in the supernal purity. A spark of blackness emerged in the sealed within the sealed, from the mystery of the Ayn Sof, a mist within matter, implanted in a ring, no white, no black, no red, no yellow, no colour at all. When He measured with the standard of measure, He made colours to provide light. Within the spark, in the innermost part, emerged a source, from which the colours are painted below; it is sealed among the sealed things of the mystery of Ayn Sof. It penetrated, yet did not penetrate its air. It was not known at all until, from the pressure of its penetration, a single point shone, sealed, supernal. Beyond this point nothing is known, so it is called reishit (beginning): the first word of all ...^[32] "

The structure of emanations has been described in various ways: Sephirot (divine attributes) and Partzufim (divine "faces"), Ohr (spiritual light and flow), Names of God and the supernal Torah, Olamot (Spiritual Worlds), a Divine Tree and Archetypal Man, Angelic Chariot and Palaces, male and female, enclothed layers of reality, inwardly holy vitality and external Kelipot shells, 613 channels ("limbs" of the King) and the divine Souls of Man. These symbols are used to describe various levels and aspects of Divine manifestation, from the Pnimi (inner) dimensions to the Hitzoni (outer).^{[citation needed]} It is solely in relation to the emanations, certainly not the Ein Sof Ground of all Being, that Kabbalah uses anthropomorphic symbolism to relate psychologically to divinity. Kabbalists debated the validity of anthropomorphic symbolism, between its disclosure as mystical allusion, versus its instrumental use as allegorical metaphor; in the language of the Zohar, symbolism "touches yet does not touch" its point.^[33]

The Sephirot (also spelled "sefirot"; singular sefirah) are the ten emanations and attributes of God with which he continually sustains the existence of the universe. The Zohar and other Kabbalistic texts elaborate on the emergence of the sephirot from a state of concealed potential in the Ein Sof until their manifestation in the mundane world. In particular, Moses ben Jacob Cordovero (known as "the Ramak"), describes how God emanated the myriad details of finite reality out of the absolute unity of Divine light via the ten sephirot, or vessels.^[34]

According to Lurianic cosmology, the sephirot correspond to various levels of creation (ten sephirot in each of the Four Worlds, and four worlds within each of the larger four worlds, each containing ten sephirot, which themselves contain ten sephirot, to an infinite number of possibilities),^[35] and are emanated from the Creator for the purpose of creating the universe. The sephirot are considered revelations of the Creator's will (ratzon),^[36] and they should not be understood as ten different "gods" but as ten different ways the one God reveals his will through the Emanations. It is not God who changes but the ability to perceive God that changes.

Divine creation by means of the Ten Sephirot is an ethical process. They represent the different aspects of Morality. Loving-Kindness is a possible moral justification found in Chessed, and Gevurah is the Moral Justification of Justice and both are mediated by Mercy which is Rachamim. However, these pillars of morality become immoral once they become extremes. When Loving-Kindness becomes extreme it can lead to sexual depravity and lack of Justice to the wicked. When Justice becomes extreme, it can lead to torture and the Murder of innocents and unfair punishment.

"Righteous" humans (tzadikim plural of Tzadik) ascend these ethical qualities of the ten sephirot by doing righteous actions. If there were no righteous humans, the blessings of God would become completely hidden, and creation would cease to exist. While real human actions are the "Foundation" (Yesod) of this universe (Malchut), these actions must accompany the conscious intention of compassion. Compassionate actions are often impossible without faith (Emunah), meaning to trust that God always supports compassionate actions even when God seems hidden. Ultimately, it is necessary to show compassion toward oneself too in order to share compassion toward others. This "selfish" enjoyment of God's blessings but only in order to empower oneself to assist others is an important aspect of "Restriction", and is considered a kind of golden mean in kabbalah, corresponding to the sefirah of Adornment (Tiferet) being part of the "Middle Column".

Moses ben Jacob Cordovero, wrote Tomer Devorah (Palm Tree of Deborah), in which he presents an ethical teaching of Judaism in the kabbalistic context of the ten sephirot. Tomer Devorah has become also a foundational Musar text.^[37]

The most esoteric Idrot sections of the classic Zohar make reference to hypostatic male and female Partzufim (Divine Personas) displacing the Sephirot, manifestations of God in particular Anthropomorphic symbolic personalities based on Biblical esoteric exegesis and midrashic narratives. Lurianic Kabbalah places these at the centre of our existence, rather than earlier Kabbalah's Sephirot, which Luria saw as broken in Divine crisis. Contemporary cognitive understanding of the Partzuf symbols relates them to Jungian archetypes of the collective unconscious, reflecting a psychologised progression from youth to sage in therapeutic healing back to the infinite Ein Sof/Unconscious, as Kabbalah is simultaneously both theology and psychology.^[38]

Medieval Kabbalists believed that all things are linked to God through these emanations, making all levels in creation part of one great, gradually descending chain of being. Through this any lower creation reflects its particular roots in supernal divinity. Kabbalists agreed with the divine transcendence described by Jewish philosophy, but as only referring to the Ein Sof unknowable Godhead. They reinterpreted the theistic philosophical concept of creation from nothing, replacing God's creative act with panentheistic continual self-emanation by the mystical Ayin Nothingness/No-thing sustaining all spiritual and physical realms as successively more corporeal garments, veils and condensations of divine immanence. The innumerable levels of descent divide into Four comprehensive spiritual worlds, Atziluth ("Closeness" – Divine Wisdom), Beriah ("Creation" – Divine Understanding), Yetzirah ("Formation" – Divine Emotions), Assiah ("Action" – Divine Activity), with a preceding Fifth World Adam Kadmon ("Primordial Man" – Divine Will) sometimes excluded due to its sublimity. Together the whole spiritual heavens form the Divine Persona/Anthropos.

Hasidic thought extends the divine immanence of Kabbalah by holding that God is all that really exists, all else being completely undifferentiated from God's perspective. This view can be defined as acosmic monistic panentheism. According to this philosophy, God's existence is higher than anything that this world can express, yet he includes all things of this world within his divine reality in perfect unity, so that the creation effected no change in him at all. This paradox as seen from dual human and divine perspectives is dealt with at length in Chabad texts.^[39]

Among problems considered in the Hebrew Kabbalah is the theological issue of the nature and origin of evil. In the views of some Kabbalists this conceives "evil" as a "quality of God", asserting that negativity enters into the essence of the Absolute. In this view it is conceived that the Absolute needs evil to "be what it is", i.e., to exist.^[41] Foundational texts of Medieval Kabbalism conceived evil as a demonic parallel to the holy, called the Sitra Achra (the "Other Side"), and the qlippoth (the "shells/husks") that cover and conceal the holy, are nurtured from it, and yet also protect it by limiting its revelation. Scholem termed this element of the Spanish Kabbalah a "Jewish gnostic" motif, in the sense of dual powers in the divine realm of manifestation. In a radical notion, the root of evil is found within the 10 holy Sephirot, through an imbalance of Gevurah, the power of "Strength/Judgement/Severity".^[42]

Gevurah is necessary for Creation to exist as it counterposes Chesed ("loving-kindness"), restricting the unlimited divine bounty within suitable vessels, so forming the Worlds. However, if man sins (actualising impure judgement within his soul), the supernal Judgement is reciprocally empowered over the Kindness, introducing disharmony among the Sephirot in the divine realm and exile from God throughout Creation. The demonic realm, though illusory in its holy origin, becomes the real apparent realm of impurity in lower Creation. In the Zohar, the sin of Adam and Eve (who embodied Adam Kadmon below) took place in the spiritual realms. Their sin was that they separated the Tree of knowledge (10 sefirot within Malkuth, representing Divine immanence), from the Tree of life within it (10 sefirot within Tiferet, representing Divine transcendence). This introduced the false perception of duality into lower creation, an external Tree of Death nurtured from holiness, and an Adam Belial of impurity.^[43] In Lurianic Kabbalah, evil originates from a primordial shattering of the sephirot of God's Persona before creation of the stable spiritual worlds, mystically represented by the 8 Kings of Edom (the derivative of Gevurah) "who died" before any king reigned in Israel from Genesis 36. In the divine view from above within Kabbalah, emphasised in Hasidic Panentheism, the appearance of duality and pluralism below dissolves into the absolute Monism of God, psychologising evil.^[44] Though impure below, what appears as evil derives from a divine blessing too high to be contained openly.^[45] The mystical task of the righteous in the Zohar is to reveal this concealed Divine Oneness and absolute good, to "convert bitterness into sweetness, darkness into light".

Kabbalistic doctrine gives man the central role in Creation, as his soul and body correspond to the supernal divine manifestations. In the Christian Kabbalah this scheme was universalised to describe harmonia mundi, the harmony of Creation within man.^[46] In Judaism, it gave a profound spiritualisation of Jewish practice. While the kabbalistic scheme gave a radically innovative, though conceptually continuous, development of mainstream Midrashic and Talmudic rabbinic notions, kabbalistic thought underscored and invigorated conservative Jewish observance. The esoteric teachings of kabbalah gave the traditional mitzvot observances the central role in spiritual creation, whether the practitioner was learned in this knowledge or not. Accompanying normative Jewish observance and worship with elite mystical kavanot intentions gave them theurgic power, but sincere observance by common folk, especially in the Hasidic popularisation of kabbalah, could replace esoteric abilities. Many kabbalists were also leading legal figures in Judaism, such as Nachmanides and Joseph Karo.

Medieval kabbalah elaborates particular reasons for each Biblical mitzvah, and their role in harmonising the supernal divine flow, uniting masculine and feminine forces on High. With this, the feminine Divine presence in this world is drawn from exile to the Holy One Above. The 613 mitzvot are embodied in the organs and soul of man. Lurianic Kabbalah incorporates this in the more inclusive scheme of Jewish messianic rectification of exiled divinity. Jewish mysticism, in contrast to Divine transcendence rationalist human-centred reasons for Jewish observance, gave Divine-immanent providential cosmic significance to the daily events in the worldly life of man in general, and the spiritual role of Jewish observance in particular.

The Kabbalah posits that the human soul has three elements, the nefesh, ru'ach, and neshamah. The nefesh is found in all humans, and enters the physical body at birth. It is the source of one's physical and psychological nature. The next two parts of the soul are not implanted at birth, but can be developed over time; their development depends on the actions and beliefs of the individual. They are said to only fully exist in people awakened spiritually. A common way of explaining the three parts of the soul is as follows:^[48]

• Nefesh (נֶפֶשׁ): the lower part, or "animal part", of the soul. It is linked to instincts and bodily cravings. This part of the soul is provided at birth.
• Ruach (רוּחַ): the middle soul, the "spirit". It contains the moral virtues and the ability to distinguish between good and evil.
• Neshamah (נְשָׁמָה): the higher soul, or "super-soul". This separates man from all other life-forms. It is related to the intellect and allows man to enjoy and benefit from the afterlife. It allows one to have some awareness of the existence and presence of God.
• Chayyah (חיה): The part of the soul that allows one to have an awareness of the divine life force itself.
• Yehidah (יחידה): The highest plane of the soul, in which one can achieve as full a union with God as is possible.

Reincarnation, the transmigration of the soul after death, was introduced into Judaism as a central esoteric tenet of Kabbalah from the Medieval period onwards, called Gilgul neshamot ("cycles of the soul"). The concept does not appear overtly in the Hebrew Bible or classic rabbinic literature, and was rejected by various Medieval Jewish philosophers. However, the Kabbalists explained a number of scriptural passages in reference to Gilgulim. The concept became central to the later Kabbalah of Isaac Luria, who systemised it as the personal parallel to the cosmic process of rectification. Through Lurianic Kabbalah and Hasidic Judaism, reincarnation entered popular Jewish culture as a literary motif.^[49]

Tzimtzum (Constriction/Concentration) is the primordial cosmic act whereby God "contracted" His infinite light, leaving a "void" into which the light of existence was poured. This allowed the emergence of independent existence that would not become nullified by the pristine Infinite Light, reconciling the unity of the Ein Sof with the plurality of creation. This changed the first creative act into one of withdrawal/exile, the antithesis of the ultimate Divine Will. In contrast, a new emanation after the Tzimtzum shone into the vacuum to begin creation, but led to an initial instability called Tohu (Chaos), leading to a new crisis of Shevirah (Shattering) of the sephirot vessels. The shards of the broken vessels fell down into the lower realms, animated by remnants of their divine light, causing primordial exile within the Divine Persona before the creation of man. Exile and enclothement of higher divinity within lower realms throughout existence requires man to complete the Tikkun olam (Rectification) process. Rectification Above corresponds to the reorganization of the independent sephirot into relating Partzufim (Divine Personas), previously referred to obliquely in the Zohar. From the catastrophe stems the possibility of self-aware Creation, and also the Kelipot (Impure Shells) of previous Medieval kabbalah. The metaphorical anthropomorphism of the partzufim accentuates the sexual unifications of the redemption process, while Gilgul reincarnation emerges from the scheme. Uniquely, Lurianism gave formerly private mysticism the urgency of Messianic social involvement.

According to interpretations of Luria, the catastrophe stemmed from the "unwillingness" of the residue imprint after the Tzimtzum to relate to the new vitality that began creation. The process was arranged to shed and harmonise the Divine Infinity with the latent potential of evil.^[50] The creation of Adam would have redeemed existence, but his sin caused new shevirah of Divine vitality, requiring the Giving of the Torah to begin Messianic rectification. Historical and individual history becomes the narrative of reclaiming exiled Divine sparks.

Kabbalistic thought extended Biblical and Midrashic notions that God enacted Creation through the Hebrew language and through the Torah into a full linguistic mysticism. In this, every Hebrew letter, word, number, even accent on words of the Hebrew Bible contain Jewish mystical meanings, describing the spiritual dimensions within exoteric ideas, and it teaches the hermeneutic methods of interpretation for ascertaining these meanings. Names of God in Judaism have further prominence, though infinite meaning turns the whole Torah into a Divine name. As the Hebrew name of things is the channel of their lifeforce, parallel to the sephirot, so concepts such as "holiness" and "mitzvot" embody ontological Divine immanence, as God can be known in manifestation as well as transcendence. The infinite potential of meaning in the Torah, as in the Ein Sof, is reflected in the symbol of the two trees of the Garden of Eden; the Torah of the Tree of Knowledge is the external, finite Halachic Torah, enclothed within which the mystics perceive the unlimited infinite plurality of meanings of the Torah of the Tree of Life. In Lurianic terms, each of the 600,000 root souls of Israel find their own interpretation in Torah, as "God, the Torah and Israel are all One".^{[citation needed]}

The reapers of the Field are the Comrades, masters of this wisdom, because Malkhut is called the Apple Field, and She grows sprouts of secrets and new meanings of Torah. Those who constantly create new interpretations of Torah are the ones who reap Her.^[51]

As early as the 1st century BCE Jews believed that the Torah and other canonical texts contained encoded messages and hidden meanings. Gematria is one method for discovering its hidden meanings. In this system, each Hebrew letter also represents a number. By converting letters to numbers, Kabbalists were able to find a hidden meaning in each word. This method of interpretation was used extensively by various schools.

In contemporary interpretation of kabbalah, Sanford Drob makes cognitive sense of this linguistic mythos by relating it to postmodern philosophical concepts described by Jacques Derrida and others, where all reality embodies narrative texts with infinite plurality of meanings brought by the reader. In this dialogue, kabbalah survives the nihilism of Deconstruction by incorporating its own Lurianic Shevirah, and by the dialectical paradox where man and God imply each other.^[52]

The founder of the academic study of Jewish mysticism, Gershom Scholem, privileged an intellectual view of the nature of Kabbalistic symbols as dialectic Theosophical speculation. In contrast, contemporary scholarship of Moshe Idel and Elliot R. Wolfson has opened a phenomenological understanding of the mystical nature of Kabbalistic experience, based on a close reading of the historical texts. Wolfson has shown that among the closed elite circles of mystical activity, medieval Theosophical Kabbalists held that an intellectual view of their symbols was secondary to the experiential. In the context of medieval Jewish philosophical debates on the role of imagination in Biblical prophecy, and essentialist versus instrumental kabbalistic debates about the relation of sephirot to God, they saw contemplation on the sephirot as a vehicle for prophecy. Judaism's ban on physical iconography, along with anthropomorphic metaphors for Divinity in the Hebrew Bible and midrash, enabled their internal visualisation of the Divine sephirot Anthropos in imagination. Disclosure of the aniconic in iconic internal psychology, involved sublimatory revelation of Kabbalah's sexual unifications. Previous academic distinction between Theosophical versus Abulafian Ecstatic-Prophetic Kabbalah overstated their division of aims, which revolved around visual versus verbal/auditory views of prophecy.^[53] In addition, throughout the history of Judaic Kabbalah, the greatest mystics claimed to receive new teachings from Elijah the Prophet, the souls of earlier sages (a purpose of Lurianic meditation prostrated on the graves of Talmudic Tannaim, Amoraim and Kabbalists), the soul of the mishnah, ascents during sleep, heavenly messengers, etc. A tradition of parapsychology abilities, psychic knowledge, and theurgic intercessions in heaven for the community is recounted in the hagiographic works Praises of the Ari, Praises of the Besht, and in many other Kabbalistic and Hasidic tales. Kabbalistic and Hasidic texts are concerned to apply themselves from exegesis and theory to spiritual practice, including prophetic drawing of new mystical revelations in Torah. The mythological symbols Kabbalah uses to answer philosophical questions, themselves invite mystical contemplation, intuitive apprehension and psychological engagement.^[54]

In bringing Theosophical Kabbalah into contemporary intellectual understanding, using the tools of modern and postmodern philosophy and psychology, Sanford Drob shows philosophically how every symbol of the Kabbalah embodies the simultaneous dialectical paradox of mystical Coincidentia oppositorum, the conjoining of two opposite dualities.^[55] Thus the Infinite Ein Sof is above the duality of Yesh/Ayin Being/Non-Being transcending Existence/Nothingness (Becoming into Existence through the souls of Man who are the inner dimension of all spiritual and physical worlds, yet simultaneously the Infinite Divine generative lifesource beyond Creation that continuously keeps everything spiritual and physical in existence); Sephirot bridge the philosophical problem of the One and the Many; Man is both Divine (Adam Kadmon) and human (invited to project human psychology onto Divinity to understand it); Tzimtzum is both illusion and real from Divine and human perspectives; evil and good imply each other (Kelipah draws from Divinity, good arises only from overcoming evil); Existence is simultaneously partial (Tzimtzum), broken (Shevirah), and whole (Tikun) from different perspectives; God experiences Himself as Other through Man, Man embodies and completes (Tikun) the Divine Persona Above. In Kabbalah's reciprocal Panentheism, Theism and Atheism/Humanism represent two incomplete poles of a mutual dialectic that imply and include each other's partial validity.^[52] This was expressed by the Chabad Hasidic thinker Aaron of Staroselye, that the truth of any concept is revealed only in its opposite.

By expressing itself using symbols and myth that transcend single interpretations, Theosophical Kabbalah incorporates aspects of philosophy, Jewish theology, psychology and unconscious depth psychology, mysticism and meditation, Jewish exegesis, theurgy, and ethics, as well as overlapping with theory from magical elements. Its symbols can be read as questions which are their own existentialist answers (the Hebrew sephirah Chokmah-Wisdom, the beginning of Existence, is read etymologically by Kabbalists as the question "Koach Mah?" the "Power of What?"). Alternative listings of the Sephirot start with either Keter (Unconscious Will/Volition), or Chokmah (Wisdom), a philosophical duality between a Rational or Supra-Rational Creation, between whether the Mitzvot Judaic observances have reasons or transcend reasons in Divine Will, between whether study or good deeds is superior, and whether the symbols of Kabbalah should be read as primarily metaphysical intellectual cognition or Axiology values. Messianic redemption requires both ethical Tikkun olam and contemplative Kavanah. Sanford Drob sees every attempt to limit Kabbalah to one fixed dogmatic interpretation as necessarily bringing its own Deconstruction (Lurianic Kabbalah incorporates its own Shevirah self shattering; the Ein Sof transcends all of its infinite expressions; the infinite mystical Torah of the Tree of Life has no/infinite interpretations). The infinite axiology of the Ein Sof One, expressed through the Plural Many, overcomes the dangers of nihilism, or the antinomian mystical breaking of Jewish observance alluded to throughout Kabbalistic and Hasidic mysticisms.^[52]

Like the rest of the rabbinic literature, the texts of kabbalah were once part of an ongoing oral tradition, though, over the centuries, much of the oral tradition has been written down.

Jewish forms of esotericism existed over 2,000 years ago. Ben Sira (born c. 170 BCE) warns against it, saying: "You shall have no business with secret things".^[56] Nonetheless, mystical studies were undertaken and resulted in mystical literature, the first being the Apocalyptic literature of the second and first pre-Christian centuries and which contained elements that carried over to later kabbalah.

Throughout the centuries since, many texts have been produced, among them the ancient descriptions of Sefer Yetzirah, the Heichalot mystical ascent literature, the Bahir, Sefer Raziel HaMalakh and the Zohar, the main text of Kabbalistic exegesis. Classic mystical Bible commentaries are included in fuller versions of the Mikraot Gedolot (Main Commentators). Cordoveran systemisation is presented in Pardes Rimonim, philosophical articulation in the works of the Maharal, and Lurianic rectification in Etz Chayim. Subsequent interpretation of Lurianic Kabbalah was made in the writings of Shalom Sharabi, in Nefesh HaChaim and the 20th-century Sulam. Hasidism interpreted kabbalistic structures to their correspondence in inward perception.^[57] The Hasidic development of kabbalah incorporates a successive stage of Jewish mysticism from historical kabbalistic metaphysics.^[58]

The first modern-academic historians of Judaism, the "Wissenschaft des Judentums" school of the 19th century, framed Judaism in solely rational terms in the emancipatory Haskalah spirit of their age. They opposed kabbalah and restricted its significance from Jewish historiography. In the mid-20th century, it was left to Gershom Scholem to overturn their stance, establishing the flourishing present-day academic investigation of Jewish mysticism, and making Heichalot, Kabbalistic and Hasidic texts the objects of scholarly critical-historical study. In Scholem's opinion, the mythical and mystical components of Judaism were at least as important as the rational ones, and he thought that they, rather than the exoteric Halakha or intellectualist Jewish philosophy, were the living subterranean stream in historical Jewish development that periodically broke out to renew the Jewish spirit and social life of the community. Scholem's magisterial Major Trends in Jewish Mysticism (1941) among his seminal works, though representing scholarship and interpretations that have subsequently been challenged and revised within the field,^[59] remains the only academic survey studying all main historical periods of Jewish mysticism.

The Hebrew University of Jerusalem has been a centre of this research, including Scholem and Isaiah Tishby, and more recently Joseph Dan, Yehuda Liebes, Rachel Elior, and Moshe Idel.^[60] Scholars across the eras of Jewish mysticism in America and Britain have included Alexander Altmann, Arthur Green, Lawrence Fine, Elliot Wolfson, Daniel Matt,^[61] Louis Jacobs and Ada Rapoport-Albert.

Moshe Idel has opened up research on the Ecstatic Kabbalah alongside the theosophical, and has called for new multi-disciplinary approaches, beyond the philological and historical that have dominated until now, to include phenomenology, psychology, anthropology and comparative studies.^[62]

Historians have noted that most claims for the authority of kabbalah involve an argument of the antiquity of authority.^[63] As a result, virtually all early foundational works pseudepigraphically claim, or are ascribed, ancient authorship. For example, Sefer Raziel HaMalach, an astro-magical text partly based on a magical manual of late antiquity, Sefer ha-Razim, was, according to the kabbalists, transmitted by the angel Raziel to Adam after he was evicted from Eden. Another famous work, the early Sefer Yetzirah, is dated back to the patriarch Abraham.^[64] This tendency toward pseudepigraphy has its roots in apocalyptic literature, which claims that esoteric knowledge such as magic, divination and astrology was transmitted to humans in the mythic past by the two angels, Aza and Azaz'el (in other places, Azaz'el and Uzaz'el) who fell from heaven (see Genesis 6:4).

As well as ascribing ancient origins to texts, and reception of Oral Torah transmission, the greatest and most innovative Kabbalists claimed mystical reception of direct personal divine revelations, by heavenly mentors such as Elijah the Prophet, the souls of Talmudic sages, prophetic revelation, soul ascents on high, etc. On this basis Arthur Green speculates, that while the Zohar was written by a circle of Kabbalists in medieval Spain, they may have believed they were channeling the souls and direct revelations from the earlier mystic circle of Shimon bar Yochai in 2nd century Galilee depicted in the Zohar's narrative.^[65] Academics have compared the Zohar mystic circle of Spain with the romanticised wandering mystic circle of Galilee described in the text. Similarly, Isaac Luria gathered his disciples at the traditional Idra assembly location, placing each in the seat of their former reincarnations as students of Shimon bar Yochai.

One point of view is represented by the Hasidic work Tanya (1797), in order to argue that Jews have a different character of soul: while a non-Jew, according to the author Shneur Zalman of Liadi (born 1745), can achieve a high level of spirituality, similar to an angel, his soul is still fundamentally different in character, from a Jewish one.^[66] A similar view is found in Kuzari, an early medieval philosophical book by Yehuda Halevi (1075–1141 CE).^[67]

Another prominent Habad rabbi, Abraham Yehudah Khein (born 1878), believed that spiritually elevated Gentiles have essentially Jewish souls, "who just lack the formal conversion to Judaism", and that unspiritual Jews are "Jewish merely by their birth documents".^[68] The great 20th-century Kabbalist Yehuda Ashlag viewed the terms "Jews" and "Gentile" as different levels of perception, available to every human soul.

David Halperin argues that the collapse of Kabbalah's influence among Western European Jews over the course of the 17th and 18th century was a result of the cognitive dissonance they experienced between the negative perception of Gentiles found in some exponents of Kabbalah, and their own positive dealings with non-Jews, which were rapidly expanding and improving during this period due to the influence of the Enlightenment.^[69]

Pinchas Elijah Hurwitz, a prominent Lithuanian-Galician Kabbalist of the 18th century and a moderate proponent of the Haskalah, called for brotherly love and solidarity between all nations, and believed that Kabbalah can empower everyone, Jews and Gentiles alike, with prophetic abilities.^[70]

The works of Abraham Cohen de Herrera (1570–1635) are full of references to Gentile mystical philosophers. Such approach was particularly common among the Renaissance and post-Renaissance Italian Jews. Late medieval and Renaissance Italian Kabbalists, such as Yohanan Alemanno, David Messer Leon and Abraham Yagel, adhered to humanistic ideals and incorporated teachings of various Christian and pagan mystics.

A prime representative of this humanist stream in Kabbalah was Elijah Benamozegh, who explicitly praised Christianity, Islam, Zoroastrianism, Hinduism, as well as a whole range of ancient pagan mystical systems. He believed that Kabbalah can reconcile the differences between the world's religions, which represent different facets and stages of the universal human spirituality. In his writings, Benamozegh interprets the New Testament, Hadith, Vedas, Avesta and pagan mysteries according to the Kabbalistic theosophy.^[71]

E. R. Wolfson provides numerous examples from the 17th to the 20th centuries, which would challenge the view of Halperin as well as the notion that "modern Judaism" has rejected or dismissed this "outdated aspect" of the religion and, he argues, there are still Kabbalists today who harbor this view. He argues that, while it is accurate to say that many Jews do and would find this distinction offensive, it is inaccurate to say that the idea has been totally rejected in all circles. As Wolfson has argued, it is an ethical demand on the part of scholars to continue to be vigilant with regard to this matter and in this way the tradition can be refined from within.^[72]

The idea that there are ten divine sephirot could evolve over time into the idea that "God is One being, yet in that One being there are Ten" which opens up a debate about what the "correct beliefs" in God should be, according to Judaism. The early Kabbalists debated the relationship of the Sephirot to God, adopting a range of essentialist versus instrumental views.^[22] Modern Kabbalah, based on the 16th century systemisations of Cordovero and Isaac Luria, takes an intermediate position: the instrumental vessels of the sephirot are created, but their inner light is from the undifferentiated Ohr Ein Sof essence.

The pre-Kabbalistic Saadia Gaon wrote that Jews who believe in reincarnation have adopted a non-Jewish belief.^[73]

Maimonides (12th century), celebrated by followers for his Jewish rationalism, rejected many of the pre-Kabbalistic Hekalot texts, particularly Shi'ur Qomah whose starkly anthropomorphic vision of God he considered heretical.^[74] Maimonides, a centrally important medieval sage of Judaism, lived at the time of the first emergence of Kabbalah. Modern scholarship views the systemisation and publication of their historic oral doctrine by Kabbalists, as a move to rebut the threat on Judaic observance by the populance misreading Maimonides' ideal of philosophical contemplation over ritual performance in his philosophical Guide for the Perplexed. They objected to Maimonides equating the Talmudic Maaseh Breishit and Maaseh Merkavah secrets of the Torah with Aristotelean physics and metaphysics in that work and in his legal Mishneh Torah, teaching that their own Theosophy, centred on an esoteric metaphysics of traditional Jewish practice, is the Torah's true inner meaning.

The Kabbalist medieval rabbinic sage Nachmanides (13th century), classic debater against Maimonidean rationalism, provides background to many kabbalistic ideas. An entire book entitled Gevuras Aryeh was authored by Yaakov Yehuda Aryeh Leib Frenkel and originally published in 1915, specifically to explain and elaborate on the kabbalistic concepts addressed by Nachmanides in his classic commentary to the Five books of Moses.

Abraham Maimonides (in the spirit of his father Maimonides, Saadiah Gaon, and other predecessors) explains at length in his Milḥamot HaShem that God is in no way literally within time or space nor physically outside time or space, since time and space simply do not apply to his being whatsoever, emphasizing the Monotheist Oneness of Divine transcendence unlike any worldly conception. Kabbalah's Panentheism expressed by Moses Cordovero and Hasidic thought, agrees that God's essence transcends all expression, but holds in contrast that existence is a manifestation of God's Being, descending immanently through spiritual and physical condensations of the divine light. By incorporating the pluralist many within God, God's Oneness is deepened to exclude the true existence of anything but God. In Hasidic Panentheism, the world is acosmic from the Divine view, yet real from its own perspective.

Around the 1230s, Rabbi Meir ben Simon of Narbonne wrote an epistle (included in his Milḥemet Mitzvah) against his contemporaries, the early Kabbalists, characterizing them as blasphemers who even approach heresy. He particularly singled out the Sefer Bahir, rejecting the attribution of its authorship to the tanna R. Neḥunya ben ha-Kanah and describing some of its content as truly heretical.^[22]

Leon of Modena, a 17th-century Venetian critic of Kabbalah, wrote that if we were to accept the Kabbalah, then the Christian trinity would be compatible with Judaism, as the Trinity seems to resemble the kabbalistic doctrine of the sephirot. This was in response to the belief that some European Jews of the period addressed individual sephirot in their prayers, although the practice was apparently uncommon. Apologists explained that Jews may have been praying for and not necessarily to the aspects of Godliness represented by the sephirot. In contrast to Christianity, Kabbalists declare that one prays only "to Him (God's Essence, male solely by metaphor in Hebrew's gendered grammar), not to his attributes (sephirot or any other Divine manifestations or forms of incarnation)". Kabbalists directed their prayers to God's essence through the channels of particular sephirot using kavanot Divine names intentions. To pray to a manifestation of God introduces false division among the sephirot, disrupting their absolute unity, dependence and dissolving into the transcendent Ein Sof; the sephirot descend throughout Creation, only appearing from man's perception of God, where God manifests by any variety of numbers.

Yaakov Emden (1697–1776), himself an Orthodox Kabbalist who venerated the Zohar,^[75] concerned to battle Sabbatean misuse of Kabbalah, wrote the Mitpaḥath Sfarim (Veil of the Books), an astute critique of the Zohar in which he concludes that certain parts of the Zohar contain heretical teaching and therefore could not have been written by Shimon bar Yochai.^[75]

Vilna Gaon (1720–1797) held the Zohar and Luria in deep reverence, critically emending classic Judaic texts from historically accumulated errors by his acute acumen and scholarly belief in the perfect unity of Kabbalah revelation and Rabbinic Judaism. Though a Lurianic Kabbalist, his commentaries sometimes chose Zoharic interpretation over Luria when he felt the matter lent itself to a more exoteric view. Although proficient in mathematics and sciences and recommending their necessity for understanding Talmud, he had no use for canonical medieval Jewish philosophy, declaring that Maimonides had been "misled by the accursed philosophy" in denying belief in the external occult matters of demons, incantations and amulets.^[76]

Views of Kabbalists regarding Jewish philosophy varied from those who appreciated Maimonidean and other classic medieval philosophical works, integrating them with Kabbalah and seeing profound human philosophical and Divine kabbalistic wisdoms as compatible, to those who polemicised against religious philosophy during times when it became overly rationalist and dogmatic. A dictum commonly cited by Kabbalists, "Kabbalah begins where Philosophy ends", can be read as either appreciation or polemic. Moses of Burgos (late 13th century) declared, "these philosophers whose wisdom you are praising end where we begin".^[77] Moses Cordovero appreciated the influence of Maimonides in his quasi-rational systemisation.^[78] From its inception, the Theosophical Kabbalah became permeated by terminology adapted from philosophy and given new mystical meanings, such as its early integration with the Neoplatonism of Ibn Gabirol and use of Aristotelian terms of Form over Matter.

Pinchas Giller and Adin Steinsaltz write that Kabbalah is best described as the inner part of traditional Jewish religion, the official metaphysics of Judaism, that was essential to normative Judaism until fairly recently.^[79][80] With the decline of Jewish life in medieval Spain, it displaced rationalist Jewish philosophy until the modern rise of Haskalah enlightenment, receiving a revival in our postmodern age. While Judaism always maintained a minority tradition of religious rationalist criticism of Kabbalah, Gershom Scholem writes that Lurianic Kabbalah was the last theology that was near predominant in Jewish life. While Lurianism represented the elite of esoteric Kabbalism, its mythic-messianic divine drama and personalisation of reincarnation captured the popular imagination in Jewish folklore and in the Sabbatean and Hasidic social movements.^[81] Giller notes that the former Zoharic-Cordoverian classic Kabbalah represented a common exoteric popular view of Kabbalah, as depicted in early modern Musar literature.^[82]

In contemporary Orthodox Judaism there is dispute as to the status of the Zohar's and Isaac Luria's (the Arizal) Kabbalistic teachings. While a portion of Modern Orthodox, followers of the Dor De'ah movement, and many students of the Rambam reject Arizal's Kabbalistic teachings, as well as deny that the Zohar is authoritative or from Shimon bar Yohai, all three of these groups accept the existence and validity of the Talmudic Maaseh Breishit and Maaseh Merkavah mysticism. Their disagreement concerns whether the Kabbalistic teachings promulgated today are accurate representations of those esoteric teachings to which the Talmud refers. The mainstream Haredi (Hasidic, Lithuanian, Oriental) and Religious Zionist Jewish movements revere Luria and the Kabbalah, but one can find both rabbis who sympathize with such a view, while disagreeing with it,^[83] as well as rabbis who consider such a view heresy. The Haredi Eliyahu Dessler and Gedaliah Nadel maintained that it is acceptable to believe that the Zohar was not written by Shimon bar Yochai and that it had a late authorship.^[84] Yechiel Yaakov Weinberg mentioned the possibility of Christian influence in the Kabbalah with the "Kabbalistic vision of the Messiah as the redeemer of all mankind" being "the Jewish counterpart to Christ."^[85]

Modern Orthodox Judaism, representing an inclination to rationalism, embrace of academic scholarship, and the individual's autonomy to define Judaism, embodies a diversity of views regarding Kabbalah from a Neo-Hasidic spirituality to Maimonist anti-Kabbalism. In a book to help define central theological issues in Modern Orthodoxy, Michael J. Harris writes that the relationship between Modern Orthodoxy and mysticism has been under-discussed. He sees a deficiency of spirituality in Modern Orthodoxy, as well as the dangers in a fundamentalist adoption of Kabbalah. He suggests the development of neo-Kabbalistic adaptions of Jewish mysticism compatible with rationalism, offering a variety of precedent models from past thinkers ranging from the mystical inclusivism of Abraham Isaac Kook to a compartmentalisation between Halakha and mysticism.^[86]

Yiḥyeh Qafeḥ, a 20th-century Yemenite Jewish leader and Chief Rabbi of Yemen, spearheaded the Dor De'ah ("generation of knowledge") movement^[87] to counteract the influence of the Zohar and modern Kabbalah.^[88] He authored critiques of mysticism in general and Lurianic Kabbalah in particular; his magnum opus was Milḥamoth ha-Shem (Wars of Hashem)^[89] against what he perceived as neo-platonic and gnostic influences on Judaism with the publication and distribution of the Zohar since the 13th Century. Rabbi Yiḥyah founded yeshivot, rabbinical schools, and synagogues that featured a rationalist approach to Judaism based on the Talmud and works of Saadia Gaon and Maimonides (Rambam). In recent years, rationalists holding similar views as those of the Dor De'ah movement have described themselves as "talmide ha-Rambam" (disciples of Maimonides) rather than as being aligned with Dor De'ah, and are more theologically aligned with the rationalism of Modern Orthodox Judaism than with Orthodox Ḥasidic or Ḥaredi communities.^[90]

Yeshayahu Leibowitz (1903–1994), an ultra-rationalist Modern Orthodox philosopher, referred to Kabbalah "a collection of "pagan superstitions" and "idol worship" in remarks given in 1990.^[91]

Kabbalah tended to be rejected by most Jews in the Conservative and Reform movements, though its influences were not completely eliminated. While it was generally not studied as a discipline, the Kabbalistic Kabbalat Shabbat service remained part of liberal liturgy, as did the Yedid Nefesh prayer. Nevertheless, in the 1960s, Saul Lieberman of the Jewish Theological Seminary of America is reputed to have introduced a lecture by Scholem on Kabbalah with a statement that Kabbalah itself was "nonsense", but the academic study of Kabbalah was "scholarship". This view became popular among many Jews, who viewed the subject as worthy of study, but who did not accept Kabbalah as teaching literal truths.

According to Bradley Shavit Artson (Dean of the Conservative Ziegler School of Rabbinic Studies)

Many western Jews insisted that their future and their freedom required shedding what they perceived as parochial orientalism. They fashioned a Judaism that was decorous and strictly rational (according to 19th-century European standards), denigrating Kabbalah as backward, superstitious, and marginal.^[92]

However, in the late 20th century and early 21st century there has been a revival in interest in Kabbalah in all branches of liberal Judaism. The Kabbalistic 12th-century prayer Anim Zemirot was restored to the new Conservative Sim Shalom siddur, as was the B'rikh Shmeh passage from the Zohar, and the mystical Ushpizin service welcoming to the Sukkah the spirits of Jewish forebears. Anim Zemirot and the 16th-century mystical poem Lekhah Dodi reappeared in the Reform Siddur Gates of Prayer in 1975. All rabbinical seminaries now teach several courses in Kabbalah—in Conservative Judaism, both the Jewish Theological Seminary of America and the Ziegler School of Rabbinic Studies of the American Jewish University in Los Angeles have full-time instructors in Kabbalah and Hasidut, Eitan Fishbane and Pinchas Giller, respectively. In Reform Judaism, Sharon Koren teaches at the Hebrew Union College-Jewish Institute of Religion. Reform rabbis like Herbert Weiner and Lawrence Kushner have renewed interest in Kabbalah among Reform Jews. At the Reconstructionist Rabbinical College, Joel Hecker is the full-time instructor teaching courses in Kabbalah and Hasidut.

According to Artson:

Ours is an age hungry for meaning, for a sense of belonging, for holiness. In that search, we have returned to the very Kabbalah our predecessors scorned. The stone that the builders rejected has become the head cornerstone (Psalm 118:22)... Kabbalah was the last universal theology adopted by the entire Jewish people, hence faithfulness to our commitment to positive-historical Judaism mandates a reverent receptivity to Kabbalah.^[93]

The Reconstructionist movement, under the leadership of Arthur Green in the 1980s and 1990s, and with the influence of Zalman Schachter Shalomi, brought a strong openness to Kabbalah and hasidic elements that then came to play prominent roles in the Kol ha-Neshamah siddur series.

Teaching of classic esoteric kabbalah texts and practice remained traditional until recent times, passed on in Judaism from master to disciple, or studied by leading rabbinic scholars. This changed in the 20th century, through conscious reform and the secular openness of knowledge. In contemporary times kabbalah is studied in four very different, though sometimes overlapping, ways.

The traditional method, employed among Jews since the 16th century, continues in learned study circles. Its prerequisite is to either be born Jewish or be a convert and to join a group of kabbalists under the tutelage of a rabbi, since the 18th century more likely a Hasidic one, though others exist among Sephardi-Mizrachi, and Lithuanian rabbinic scholars. Beyond elite, historical esoteric kabbalah, the public-communally studied texts of Hasidic thought explain kabbalistic concepts for wide spiritual application, through their own concern with popular psychological perception of Divine Panentheism.^[42]

A second, new universalist form, is the method of modern-style Jewish organisations and writers, who seek to disseminate kabbalah to every man, woman and child regardless of race or class, especially since the Western interest in mysticism from the 1960s. These derive from various cross-denominational Jewish interests in kabbalah, and range from considered theology to popularised forms that often adopt New Age terminology and beliefs for wider communication. These groups highlight or interpret kabbalah through non-particularist, universalist aspects.^[94]

A third way are non-Jewish organisations, mystery schools, initiation bodies, fraternities and secret societies, the most popular of which are Freemasonry, Rosicrucianism and the Golden Dawn, although hundreds of similar societies claim a kabbalistic lineage. These derive from syncretic combinations of Jewish kabbalah with Christian, occultist or contemporary New Age spirituality. As a separate spiritual tradition in Western esotericism since the Renaissance, with different aims from its Jewish origin, the non-Jewish traditions differ significantly and do not give an accurate representation of the Jewish spiritual understanding (or vice versa).^[95]

Fourthly, since the mid-20th century, historical-critical scholarly investigation of all eras of Jewish mysticism has flourished into an established department of university Jewish studies. Where the first academic historians of Judaism in the 19th century opposed and marginalised kabbalah, Gershom Scholem and his successors repositioned the historiography of Jewish mysticism as a central, vital component of Judaic renewal through history. Cross-disciplinary academic revisions of Scholem's and others' theories are regularly published for wide readership.^[96]

In recent decades, Kabbalah has seen a resurgence of interest, with several modern groups and individuals exploring its profound teachings. These contemporary interpretations of Kabbalah offer a fresh perspective on this ancient mystical tradition, often bridging the gap between traditional wisdom and modern thought. Some of these interpretations emphasize universalist and philosophical approaches, seeking to enrich secular disciplines through the lens of Kabbalistic insights. Others have gained attention for their unique blends of spirituality and popular culture, attracting followers from diverse backgrounds. These modern expressions of Kabbalah showcase its enduring appeal and relevance in today's world.^{[citation needed]}

Bnei Baruch is a group of Kabbalah students, based in Israel. Study materials are available in over 25 languages for free online or at printing cost. Michael Laitman established Bnei Baruch in 1991, following the passing of his teacher, Ashlag's son Rav Baruch Ashlag. Laitman named his group Bnei Baruch (sons of Baruch) to commemorate the memory of his mentor. The teaching strongly suggests restricting one's studies to 'authentic sources', kabbalists of the direct lineage of master to disciple.^[97][98]

The Kabbalah Centre was founded in the United States in 1965 as The National Research Institute of Kabbalah by Philip Berg and Rav Yehuda Tzvi Brandwein, disciple of Yehuda Ashlag's. Later Philip Berg and his wife re-established the organisation as the worldwide Kabbalah Centre.^{[99][failed verification]} The organization's leaders "vehemently reject" Orthodox Jewish identity.^[100]

The Kabbalah Society, run by Warren Kenton, an organisation based instead on pre-Lurianic Medieval Kabbalah presented in universalist style. In contrast, traditional kabbalists read earlier kabbalah through later Lurianism and the systemisations of 16th-century Safed.^{[citation needed]}

The New Kabbalah, website and books by Sanford L. Drob, is a scholarly intellectual investigation of the Lurianic symbolism in the perspective of modern and postmodern intellectual thought. It seeks a "new kabbalah" rooted in the historical tradition through its academic study, but universalised through dialogue with modern philosophy and psychology. This approach seeks to enrich the secular disciplines, while uncovering intellectual insights formerly implicit in kabbalah's essential myth:^[101]

By being equipped with the nonlinear concepts of dialectical, psychoanalytic, and deconstructive thought we can begin to make sense of the kabbalistic symbols in our own time. So equipped, we are today probably in a better position to understand the philosophical aspects of the kabbalah than were the kabbalists themselves.^[102]

The Kabbalah of Information is described in the 2018 book From Infinity to Man: The Fundamental Ideas of Kabbalah Within the Framework of Information Theory and Quantum Physics written by Ukrainian-born professor and businessman Eduard Shyfrin. The main tenet of the teaching is "In the beginning He created information", rephrasing the famous saying of Nahmanides, "In the beginning He created primordial matter and He didn't create anything else, just shaped it and formed it."^[103]

Since the 18th century, Jewish mystical development has continued in Hasidic Judaism, turning kabbalah into a social revival with texts that internalise mystical thought. Among different schools, Chabad-Lubavitch and Breslav with related organisations, give outward looking spiritual resources and textual learning for secular Jews. The Intellectual Hasidism of Chabad most emphasises the spread and understanding of kabbalah through its explanation in Hasidic thought, articulating the Divine meaning within kabbalah through human rational analogies, uniting the spiritual and material, esoteric and exoteric in their Divine source:

Hasidic thought instructs in the predominance of spiritual form over physical matter, the advantage of matter when it is purified, and the advantage of form when integrated with matter. The two are to be unified so one cannot detect where either begins or ends, for "the Divine beginning is implanted in the end and the end in the beginning" (Sefer Yetzira 1:7). The One God created both for one purpose – to reveal the holy light of His hidden power. Only both united complete the perfection desired by the Creator.^[104]

From the early 20th century, Neo-Hasidism expressed a modernist or non-Orthodox Jewish interest in Jewish mysticism, becoming influential among Modern Orthodox, Conservative, Reform and Reconstructionalist Jewish denominations from the 1960s, and organised through the Jewish Renewal and Chavurah movements. The writings and teachings of Zalman Schachter-Shalomi, Arthur Green, Lawrence Kushner, Herbert Weiner and others, has sought a critically selective, non-fundamentalist neo- Kabbalistic and Hasidic study and mystical spirituality among modernist Jews. The contemporary proliferation of scholarship by Jewish mysticism academia has contributed to critical adaptions of Jewish mysticism. Arthur Green's translations from the religious writings of Hillel Zeitlin conceive the latter to be a precursor of contemporary Neo-Hasidism. Reform rabbi Herbert Weiner's Nine and a Half Mystics: The Kabbala Today (1969), a travelogue among Kabbalists and Hasidim, brought perceptive insights into Jewish mysticism to many Reform Jews. Leading Reform philosopher Eugene Borowitz described the Orthodox Hasidic Adin Steinsaltz (The Thirteen Petalled Rose) and Aryeh Kaplan as major presenters of Kabbalistic spirituality for modernists today.^[105]

The writings of Abraham Isaac Kook (1864–1935), first chief rabbi of Mandate Palestine and visionary, incorporate kabbalistic themes through his own poetic language and concern with human and divine unity. His influence is in the Religious Zionist community, who follow his aim that the legal and imaginative aspects of Judaism should interfuse:

Due to the alienation from the "secret of God" [i.e. Kabbalah], the higher qualities of the depths of Godly life are reduced to trivia that do not penetrate the depth of the soul. When this happens, the most mighty force is missing from the soul of nation and individual, and Exile finds favor essentially... We should not negate any conception based on rectitude and awe of Heaven of any form—only the aspect of such an approach that desires to negate the mysteries and their great influence on the spirit of the nation. This is a tragedy that we must combat with counsel and understanding, with holiness and courage.^[106]

In several important areas of his history of the Kabbalah, Gershom Scholem investigates and considers the evidence of an interactivity of influence between the medieval Kabbalists of Provence and the Cathar heresy which was also prevalent in the region at the same time that the earliest works of medieval Kabbalah were written.^[107]

Nathaniel Deutsch writes:

Initially, these interactions [between Mandaeans and Jewish mystics in Babylonia from Late Antiquity to the medieval period] resulted in shared magical and angelological traditions. During this phase the parallels which exist between Mandaeism and Hekhalot mysticism would have developed. At some point, both Mandaeans and Jews living in Babylonia began to develop similar cosmogonic and theosophic traditions involving an analogous set of terms, concepts, and images. At present it is impossible to say whether these parallels resulted primarily from Jewish influence on Mandaeans, Mandaean influence on Jews, or from cross fertilization. Whatever their original source, these traditions eventually made their way into the priestly – that is, esoteric – Mandaean texts ... and into the Kabbalah.^[108]: 222

R.J. Zwi Werblowsky suggests Mandaeism has more commonality with Kabbalah than with Merkabah mysticism such as cosmogony and sexual imagery. The Thousand and Twelve Questions, Scroll of Exalted Kingship, and Alma Rišaia Rba link the alphabet with the creation of the world, a concept found in Sefer Yetzirah and the Bahir.^[108]: 217 Mandaean names for uthras (angels or guardians) have been found in Jewish magical texts. Abatur appears to be inscribed inside a Jewish magic bowl in a corrupted form as "Abiṭur".
