top. Here the surrounding white represents the Ein Sof, the black circle represents the Chalal vacated "space", and the thin white line represents the "thin" illumination of the Kav, derived from the Ohr Ein Sof, but able to illuminate into the Chalal on its own terms. This representation is then augmented by a second, similar diagram, where the successive, unfolding Five Worlds, each with 10 successive Sephirot, are shown within the original circle as a series of concentric circles. The descending chain of Worlds proceeds in the diagram towards the centre of the circle, representing our lowest, physical realm. Each successive World and Sephirah is a successively smaller concentric circle, representing diminished, more constricted Divinity. The same Kav line is still shown connecting the outer Ein Sof to the centre of the circle, as the light of the Kav is the origin of all Creation after the Tzimtzum, though its light undergoes innumerable second tzimtzumim, toward the circle's centre. The utilisation here of concentric circles, or spheres is also significant, as with each subsequent lower step, the light encompasses" (sovev - "surrounds") that level of "immanent" (mimalei"-"filled") creation. Each of the Sephirot comprises both an encompassing light vested in its immanent vessel. Each World similarly incorporates its own relative level of Divine transcendence, illuminating its own level of Divine immanence. In the 10 Sefirot: Ohrot and Keilim - Lights and Vessels The 10 Sephirot describe the emanations, or attributes of God in Kabbalah. The Ein Sof ("Limitless") is the unknowable, undifferentiated, infinite Divine essence. The 10 emanations of the Sephirot enable the Creation to know God, and become God's attributes that reveal Divinity. They are also the channels through which all of Creation is continuously substained from nothing, as in the Kabbalistic scheme, Creation is continuous and God is the only true existence. A "Chain of Progression" (Seder hishtalshelus) of descending "Worlds", including the Four Worlds, links the Ein Sof with our physical realm. Each of the Sephirot is said to consist of a "light" (an ohr) that is vested in a "vessel" (a kli ; plural: keilim ). Generally speaking, the light is simple and undifferentiated, as it stems originally from the Ohr Ein Sof ("The Light of the Ein Sof"), God's infinite light. It represents Divine revelation in the world. It is associated with the Kabbalistic Divine Name of Ban. The differentiation between the 10 Sephirot, each with
