This is the first part of Eliphas Levi's last great descourse on the mysteries of occultism that was continued and concluded in The Great Secret. In it, Levi examines with great precision and insight the inner meanings of Qabalism and their relationship to the occult sciences. Part One is a commentary on the Spihra Dzeniuta by Simeon Ben-Jochal, which includes an examination of the affinities between Qabalism and Freemasonry. Part Two pursues the correspondences between Qabalism, Numerology and the Tarot. This edition includes an appendix by Papus (Dr. Gerard Encausse) summarizing Levi's doctrines and teachings and supplying some fascinating information on some of the master's many disciples.
