Within the descending Four Worlds of Creation, each successive realm perceives Divinity less and apparent independence more. The highest realm "Atziluth-Emanation", termed the "Realm of Unity", is distinguished from the lower three realms, termed the "Realm of Separation", by still having no self-awareness; absolute Divine Unity is revealed and Creation is nullified in its source. The lower three Worlds feel progressive degrees of independence from God. Where lower Creation can mistake the different Divine emanations as plural, Atziluth feels their non-existent unity in God. Within the constricted appearance of Creation, God is revealed through various and any plural numbers. God uses each number to represent a different supernal aspect of reality that He creates, to reflect their comprehensive inclusion in His absolute Oneness: 10 Sephirot, 12 Partzufim, 2 forms of Light, 2 Partzufim and 3 Heads in Keter, 4 letters of the Tetragrammaton, 22 letters of the Hebrew alphabet, 13 Attributes of Mercy, etc. All such forms when traced back to their source in God's infinite light, return to their state of absolute Oneness. This is the consciousness of Atziluth. In Kabbalah, this perception is considered subconsciously innate to the souls of Israel, rooted in Atzilut. The souls of the Nations are elevated to this perception through adherence to the 7 Laws of Noah, that bring them to absolute Divine Unity and away from any false plural perspectives.
