In the Judeo-Christian scriptures, in Hebrew, the word Babylon does not appear; instead, it is spelled בבל BBL (Babel). Babel is an important symbol with many meanings, primarily as a symbol of degenerated humanity.
"We must destroy Babylon the Great, the mother of all fornication and abominations of the Earth. Obviously, Babylon is our psychological city, populated by the psychic aggregates that we carry within our interior." - Samael Aun Weor, The Gnostic Bible: The Pistis Sophia Unveiled
