Thelema () is a Western esoteric and occult social and 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 divine and individual 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.
