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.
