Ein Sof

Ein Sof (אין סוף; lit. meaning Limitlessness), also known as The Realm of Everything and Nothing, Paradoxical Space, and The Sea of Absolute Zero, is a realm that exists outside all of Creation, encompassing it in its totality. It is beyond even Aztiluth and A"K. The realm is ruled by the mysterious Nihil, who slumbers there for all Eternity.

Summary
Ein Sof is is the Apex of all Existence, existing beyond Creation itself. It is beyond even A"K which is the highest subgradient of reality in which it makes up the sum total of a set of infinite hierarchies containing infinite hierarchies and can only be described with an ℵ1. All concepts and notions of duality, physics, infinity, time, space, and even meta-concepts of existence are completely meaningless here. In Zenith Space, everything and nothing happens all at once regardless of all contradictions on a logical and metaphysical level, making any system of duality and plurality trivial.

Trivia

 * Ein Sof in Kabbalah is the state God was in prior to self-manifestation. The term was first used by Azriel of Gerona, one of the most important Kabbalists at that time, who held Neoplatonic beliefs and thought that God can have no thought, no desire, or action as all of these are negated by it. It is the origin of the Ohr Ein Sof (The Divine Infinite Light).
 * In Lunaric Kabbalah, the Tzimtzum (Self-Withdrawal), which is the first act of Creation, takes place within the Ein Sof to create an empty void from which all of Creation springs from.
 * Ein Sof springs from the concept of Ayin, which is the Nonexistence beyond Nonexistence and Existence and cannot be defined. In the Tzimtzum's order of de-evolution into our physical creation, Ein Sof is defined as 00.
