There is some confusion about Babalon’s name. Some people call her Babylon (with the y) but that is incorrect for a few really interesting reasons. Quoting from the “Thelemapedia”(lol)
The name Babalon may derive from several sources. Firstly, there is the obvious resemblance to Babylon. Babylon was a major city in Mesopotamia, part of the Sumerian culture. Coincidentally, the Sumerian deity Ishtar bears an uncanny resemblance to the Crowleyan Babalon. Babylon itself is a city that is referred to in several places in the Bible, usually as an image of a once-glorious paradise that has fallen into ruin, a warning against the evils of decadence:
‘And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory. And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird. For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies. And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues. For her sins have reached unto heaven, and God hath remembered her iniquities’.
A second possibility is from the Enochian word BABALOND, which is translated a harlot. This is most probable, given that The Vision and the Voice was obtained by Crowley through skrying, after he had conducted invocations using the Enochian system of magick.
Crowley probably chose the spelling of Babalon for its Qabalistic significance. By replacing the letter ‘y’ with an ‘a’, the word ‘AL’ appears in the center. The whole then naturally breaks into Bab-al-on. ‘Bab’ is Arabic for a door, or gate. ‘AL’ is the Key of Liber Legis, and is also a Qabalistic title of God, meaning ‘The One’ in Hebrew. ‘On’ is the name of the Egyptiancity that the Greeks called Heliopolis, the City of the Pyramids. By gematria, Babalon sums to 156, which is the number of squares on each of the elemental Enochian tablets of Dee and Kelly. These tablets are themselves identified with the City of the Pyramids, with each square being the base of a pyramid.
Within the Gnostic Mass, Babalon is mentioned in the Gnostic Creed:
And I believe in one Earth, the Mother of us all, and in one Womb wherein all men are begotten, and wherein they shall rest, Mystery of Mystery, in Her name BABALON.[
Here, Babalon is identified with Binah on the Tree of Life, the sphere that represents the Great Sea and such mother-goddesses as Isis, Bhavani, and Ma’at. Moreover, she represents all physical mothers. Bishops T. Apiryon and Helena write:
BABALON, as the Great Mother, represents MATTER, a word which is derived from the Latin word for Mother. She is the physical mother of each of us, the one who provided us with material flesh to clothe our naked spirits; She is the Archetypal Mother, the Great Yoni, the Womb of all that lives through the flowing of Blood; She is the Great Sea, the Divine Blood itself which cloaks the World and which courses through our veins; and She is Mother Earth, the Womb of All Life that we know.
