Liber Astarte vel Liber Berylli

This Thelemic text outlines a devotional form of practice centered on intimate identification with a chosen divine image or ideal. Significant for showing Crowley’s interest in religious devotion within a magical framework, it offers readers a disciplined method of contemplation, prayer, and sustained devotional concentration.

Aleister Crowley (1875–1947) was an English occultist, ceremonial magician, poet, and religious innovator who founded Thelema, a modern esoteric system centered on will, ritual, and spiritual liberation. His many books, including Liber AL vel Legis and Magick in Theory and Practice, made him one of the most influential figures in twentieth-century occult literature.
