The Babalon Working was a series of magic ceremonies or rituals performed from January to March, 1946 by author, pioneer rocket-fuel scientist, and occultist Jack Parsons and Scientology founder L. Ron Hubbard.[1] This ritual was essentially designed to manifest an individual incarnation of the archetypal divine feminine called Babalon. The project was based on the ideas of Aleister Crowley, and his description of a similar project in his 1917 novel Moonchild.
