Any direct creations of the Infinite Light would be of infinite number, and would not be actual creations at all, as they would remain totally nullified ("bittul") to the Infinite Light, and would have no independent self-awareness. Rather it is only through the restrictions of the Sephirot and the descending "Chain of Progression" (Seder hishtalshelus), that the Worlds could unfold. In the descending chain of Worlds from the Infinite to our finite realm, the creative flow of Divine light encapsulated in the Sephirot, undergoes countless restrictions, diminutions and veilings, to progressively hide Divinity.
