From Greek "baptizein" or "baptizo" which originates from "bapto," "to dip." An ancient ritual visible in some form within all the world's religions, that symbolizes the descent of the energy of the "water of life" or primeval womb (chaos) as a blessing upon the soul who seeks to become pure of blemish.   In the esoteric aspect, baptism is the absorption of the image of God (Tzalem) by means of sexual transmutation.

"The Baptism is a pact of sexual magic. When we fulfill the pact of sexual magic, then we reach the Self-realization of the Being." - Samael Aun Weor, The Pistis Sophia Unveiled
