New religious movement founded by Aleister Crowley
Thelema () is a Western esoteric and occult social or spiritual philosophy and a new religious movement founded in the early 1900s by Aleister Crowley (1875–1947), an English writer, mystic, occultist, and ceremonial magician. Central to Thelema is the concept of discovering and following one's True Will, a unique purpose that transcends ordinary desires. Crowley's system begins with The Book of the Law, a text he maintained was dictated to him by a non-corporeal entity named Aiwass.
