Following some brief involvement with Marxism in 1939, Parsons converted to Thelema, the new religious movement founded by the English occultist Aleister Crowley.The Babalon Working 1946: L. Ron Hubbard, John Whiteside Parsons, and the Practice of Enochian Magic (jstor.org)
In the spring of 1946 L. Ron Hubbard and John W. Parsons performed a series of magical rituals with the aim of incarnating the Thelemic goddess Babalon in a human being. Hubbard’s cooperation with Parsons, known as the Babalon Working, remains one of the most controversial events in Hubbard’s pre-Scientology days. This article sets out to describe the content of the magical rituals, as well as their purpose. It is argued that in order to fully understand these events, it is necessary to approach the Babalon Working from the study of Western esotericism in general, and the study of Enochian magic in particular.- Thelema (Wikipedia)
Thelema (/θəˈliːmə/) is a Western esoteric and occult social or spiritual philosophy, as well as a new religious movement that was founded in the early 1900s by Aleister Crowley (1875–1947), an English writer, mystic, occultist, and ceremonial magician. Central to Thelema is the idea of discovering and following one’s True Will, a unique purpose and calling that goes beyond ordinary desires. Crowley’s system begins with The Book of the Law, a text he said was dictated to him by an entity named Aiwass. This foundational work lays out key principles, including the central axiom “Do what thou wilt shall be the whole of the Law”. This principle emphasizes personal freedom and the pursuit of one’s true path, while being guided by love and finding one’s authentic purpose.
