An introduction to ceremonial magic and Qabalah by the man believed to be the last living Adept of the Hermetic Order of the Golden Dawn.

The Tree of Life, written by the occultist and ceremonial magician Israel Regardie, is the most comprehensive introduction available to the Golden Dawn system of initiation, a movement that greatly influenced modern esoteric traditions. It also serves as an ideal introduction to the numerous complex and obscure mystical writings of Aleister Crowley, whom the author served for a time as a personal secretary, and includes practical exercises for developing the will and the imagination.
