Ein-Sof, the Infinite God, has no static, definable form. Instead, the Kabbalists conceive God, the world and humanity as evolving together through, and thus embodying, a number of distinct stages and aspects, with later stages opposing, but at the same time encompassing, earlier ones. The Kabbalistýs God is both perfectly simple and infinitely complex, nothing and everything, hidden and revealed, reality and illusion, creator of man and created by man,. As Ein-Sof evolves it is progressively revealed as "nothing whatsoever" (Ayin), the totality of being, the Infinite Will (Ratzon) , Thought and Wisdom, the embodiment of all value and significance (the Sefirot), the wedding of male and female, and ultimately the union of all contradictions. Ein-Sof is both the totality of this dialectic and each of the points along the way. Ein-Sof must be constantly redefined, as by its very nature, it is in a constant process of self-creation and redefinition. This self-creation is actually embodied and perfected in the creativity of humanity, who through practical, ethical, intellectual and spiritual activities, strives to redeem and perfect a chaotic, contradictory and imperfect world.
