Four Worlds

Enumeration

The Worlds are formed by the Ohr Mimalei Kol Olmin, the Divine creative light that "Fills all Worlds" immanently, according to their particular spiritual capacity to receive. The 10 sephirot attributes and 12 basic partzufim personas shine in each world (though not yet manifestly in Adam Kadmon), as well as more specific Divine manifestations. In Lurianic Kabbalah, the partzufim dynamically interact with each other, and sublime levels are enclothed within lower existences, as their concealed soul. Nonetheless, in each World, particular sephirot and partzufim predominate. The Five Worlds in descending order:

1. Adam Kadmon (A"K, אָדָם קַדְמוֹן) meaning Primordial Man. The anthropomorphic metaphor "Adam" denotes the Yosher (Upright) configuration of the sephirot in the form of Man, though not yet manifest. "Kadmon" signifies "primary of all primaries", the first pristine emanation, still united with the Ein Sof. Adam Kadmon is the realm of Keter Elyon (Supernal Crown of Will), "the lucid and luminous light" (Tzachtzachot), "the pure lucid sephirot which are concealed and hidden" in potential. Containing the future emergence of Creation, it is Divine light with no vessels, the manifestation of the specific Divine plan for Existence, within Creation (after the Tzimtzum in Lurianic Kabbalah). In Lurianism, the lights from A"K precipitate Tohu and Tikun. As Keter is elevated above the sephirot, so Adam Kadmon is supreme above the Worlds, and generally only Four Worlds are referred to.
2. Atziluth (אֲצִילוּת), meaning World of Emanation, also "Close." On this level the light of the Ein Sof (Infinite Divine "without end") radiates and is still united with its source. This supernal revelation therefore precludes the souls and Divine emanations in Atzilus from sensing their own existence. In Atzilus the 10 sephirot emerge in revelation, with Chochma (Wisdom) dominating, all is nullification of essence (Bittul HaEtzem) to Divinity, not considered created and separate. The last sephirah Malchut (Kingdom) is the "Divine speech" of Genesis 1, through which lower Worlds are sustained.
3. Beri'ah (בְּרִיאָה or alternatively בְּרִיָּה), meaning World of Creation. On this level is the first concept of creatio ex nihilo (Yesh miAyin), however without yet shape or form, as the creations of Beriah sense their own existence, though in nullification of being (Bittul HaMetzius) to Divinity. Beriah is the realm of the "Divine Throne", denoting the sephirot configuration of Atzilus descending into Beriah like a King on a Throne. The sephirah Binah (Understanding) predominates, Divine intellect. Also called the "Higher Garden of Eden". The Highest Ranking Angels are in Beriah.
4. Yetzirah (יְצִירָה), meaning World of Formation. On this level the created being assumes shape and form. The emotional sephirot Chesed to Yesod predominate, the souls and angels of Yetzirah worship through Divine emotion and striving, as they sense their distance from the Understanding of Beriah. This ascent and descent channels the Divine vitality down through the Worlds, furthering the Divine purpose. Therefore, in Yetzirah are the main angels, such as Seraphim, denoting their burning consummation in Divine emotion. Also called the "Lower Garden of Eden".
5. Assiah (עֲשִׂיָּה), meaning World of Action. On this level the creation is complete, differentiated and particular, due to the concealment and diminution of the Divine vitality. However, it is still on a spiritual level. The angels of Asiyah function on the active level, as the sephirah Malchut (fulfilment in Kingship) predominates. Below spiritual Asiyah is Asiyah Gashmi ("Physical Asiyah"), the final, lowest realm of existence, our material Universe with all its creations. The last two sephirot of Asiyah channel the lifeforce into Physical Asiyah.

Meaning

These four worlds are spiritual, Heavenly realms in a descending chain, although the lowest world of Assiah has both a spiritual and a physical aspect. The physical level of Assiah is our physical finite realm, including the cosmological Universe studied by Science. Consequently, as Kabbalah is a metaphysical study, its reference to Ohr ("light") is a metaphor for Divine emanation, and the terms "higher" and "lower" are metaphors for closer and further from Divine consciousness and revelation.

The 16th-century systemisation of Kabbalah by Moshe Cordovero brought the preceding interpretations and schools into their first complete rational synthesis. Subsequent doctrines of Kabbalah from Isaac Luria, describe an initial Tzimtzum (withdrawal of the universal Divine consciousness that preceded Creation) to "allow room" for created beings on lower levels of consciousness. Lower levels of consciousness require the self-perception of independent existence, by the created beings on each level, to prevent their loss of identity before the magnificence of God. This illusion increases with more force in each subsequent descending realm. The number of graduations between the Infinite and the finite, is likewise infinite, and arises from innumerable, progressively strong concealments of the Divine light. Nonetheless, the four worlds represent fundamental categories of Divine consciousness from each other, which delineates their four descriptions. Consequently, each world also psychologically represents a spiritual rung of ascent in human consciousness, as it approaches the Divine.

Kabbalah distinguishes between two types of Divine light that emanate through the 10 Sephirot (Divine emanations) from the Infinite (Ein Sof), to create or affect reality. The continual flow of an immanent lower light ("Mimalei Kol Olmin"), the light that "fills all worlds" is the creating force in each descending world that itself continually brings into being from nothing, everything in that level of existence. It is this light that undergoes the concealments and contractions as it descends downward to create the next level, and adapts itself to the capacity of each created being on each level. A transcendent higher light ("Sovev Kol Olmin"), the light that "surrounds all worlds" would be the manifestation on a particular level of a higher light above the capacity of that realm to contain. This is ultimately rooted in the infinite light ("Ohr Ein Sof") that preceded Creation, the Tzimtzum and the Sephirot, rather than the source of the immanent light in the "Kav" (first emanation of creation after the Tzimtzum), in the teachings of Isaac Luria. Consequently, all the worlds are dependent for their continual existence on the flow of Divinity they constantly receive from the Divine Will to create them. Creation is continuous. The faculty of Divine Will is represented in the Sephirot (10 Divine emanations) by the first, supra-conscious Sephirah of "Keter"-Crown, that transcends the lower 9 Sephirot of conscious intellect and emotion. Once the Divine Will is manifest, then it actualises Creation through Divine Intellect, and "subsequently" Divine Emotion, until it results in action. The reference to temporal cause and effect is itself a metaphor. The psychology of man also reflects the "Divine psychology" of the Sephirot, as "Man is created in the image of God" (Genesis 1:27). In man the activation of willpower through intellect and emotion until deed, requires time and subsequent cause and effect. In the Divine Sephirot and their activation of Creation, this does not apply, as limitations only apply to Creation.

The Book of Job states that "from my flesh I see God". In Kabbalah and Hasidism this is understood to refer to the correspondence between the "Divine psychology" of the Four Worlds and the Sephirot, with human psychology and the Sephirot in the soul of man. From understanding the Kabbalistic description of the human soul, we can grasp the meaning of the Divine scheme. Ultimately, this is seen as the reason that God chose to emanate His Divinity through the 10 Sephirot, and chose to create the corresponding chain of four Worlds (called the "Seder hishtalshelus"-"order of development"). He could have chosen to bridge the infinite gap between the Ein Sof and our World by a leap of Divine decree. Instead the Sephirot and Four Worlds allow man to understand Divinity through Divine manifestation, by understanding himself. The verse in Genesis of this correspondence also describes the feminine half of Creation: (Genesis 1:27) "So God created man in His own image, in the image of God created He him, male and female created He them". Consequently, some of the Sephirot are feminine, and the Shechina (immanent Divine presence) is seen as feminine. It is the intimate relationship between the Divine sceme of four World and man, that allows man's ascent more easily to Divine consciousness (see Dveikus).
