Thelema (/θəˈliːmə/) 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 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. This work outlines key principles, including the axioms "Do what thou wilt shall be the whole of the Law" and "love is the law, love under will", emphasizing personal freedom and the pursuit of one's true path.
The Thelemic cosmology features deities inspired by ancient Egyptian religion. The highest deity is Nuit, the night sky symbolized as a naked woman covered in stars, representing the ultimate source of possibilities. Hadit, the infinitely small point, symbolizes manifestation and motion. Ra-Hoor-Khuit, who is believed to be a form of Horus, represents the Sun and active energies of Thelemic magick. Crowley believed that discovering and following one's True Will is the path to self-realization and personal fulfillment, often referred to as the Great Work. The Creed of the Gnostic Mass also professes a belief in Chaos, Babalon, and Baphomet.
