In the A∴A∴ system of attainment, after the adept has achieved the Knowledge and Conversation with their Holy Guardian Angel, they then must cross the great Abyss, where they meet Choronzon, who will tempt them to hold on to their subjective self and become trapped in their realm of illusion. To escape the Abyss, the adept gives up their deepest sense of earthly identity, in the symbolic gesture of pouring out their blood into the Cup of Babalon. The adept then becomes as a Babe in the Womb of Babalon—impregnated by Pan—and their lifeless Self becomes as a pile of dust, taking rest in the City of the Pyramids, which lies under the Night of Pan. This is why it is called Night—it represents the lightless Womb, and also the time before the dawning of the new Sun (or rather, the new Self). They then wait in this sublime state until they are ready to move on to the next stage, and become “born” again from the Great Mother of Babalon, begotten by Pan.
Within the mystical system of Crowley, the adept reaches a final stage where he or she must cross the Abyss, that great wilderness of nothingness and dissolution. Choronzon is the dweller there, and his job is to trap the traveler in his meaningless world of illusion. However, Babalon is on just the other side, beckoning. If the adept gives himself to her—the symbol of this act is the pouring of the adept’s blood into her graal—he becomes impregnated in her, then to be reborn as a master and a saint that dwells in the City of the Pyramids.
As the dancer whirls, she chants in a strange, slow voice, quickening as she goes: Lo! I gather up every spirit that is pure, and weave him into my vesture of flame. I lick up the lives of men, and their souls sparkle from mine eyes. I am the mighty sorceress, the lust of the spirit. And by my dancing I gather for my mother Nuit the heads of all them that are baptized in the waters of life. I am the lust of the spirit that eateth up the soul of man. I have prepared a feast for the adepts, and they that partake thereof shall see God. - 5th Aethyr of The Vision and the Voice
