The Key of the Mysteries by Eliphas Levi collection and Aleister Crowley NEUF

Eliphas Levi (1810-1875), born Alphonse Louis Constant, was a sage, poet and author of over twenty esoteric books. He began writing at 22 years of age and was imprisoned twice for the critical nature of his work. Eliphas Levi was steeped in the Western occult tradition and a master of the Rosicrucian interpretation of the Qabalah, which forms the basis of magic as practiced in the West today. The "Key of the Mysteries" represents the culmination of Levis thoughts and is written with subtle and delicate irony. It reveals the mysteries of religion and the secrets of the Qabalah, providing a sketch of the prophetic theology of numbers. The mysteries of nature, such as spiritualism and fluidic phantoms, are explored. Magical mysteries, the Theory of the Will with its 22 axioms are divulged. And finally it offers "the great practical secrets." The true greatness of this work, however, lies in its ability to place occult thought firmly in Western religious traditions. For Levi, the study of the occult was the study of a divine science, the mathematics of God.
