“My Rosicrucian Adventure” by Israel Regardie

"What do you know about Real Magick, The Golden Dawn, True Rosicrucian, or the Western Esoteric Tradition? Dr. Regardie relates his own experience in those secret societies which have exerted such a great influence on the development of modern Occultism. He lifts the cloak of mystery which has shrouded these organizations since their heyday in the last half of the 19th century and tells what really went on behind the closed doors of the Hermetic Order of the Golden Dawn, the Theosophist Society, the Rosicrucian Fraternity, and the Masonic Lodge. From his close personal association Regardie reveals the true nature and actions of such leading Occult authorities as Aleister Crowley, S.L. MacGregor Mathers, Dr. W.W. Westcott and Dion Fortune.

This facinating book had been out of print and highly sought after for many years since its first publication in 1936. Reprinted in 1971 with a new introduction and postscript by Dr. Regardie giving further details of the rites and rituals which he was under oath not to reveal at the time of the first printing of this work. My Rosicrucian Adventure discusses both the theories behind the ceremonial grades of the Golden Dawn and the initiation rites as they were really practiced by the Order. Fear of recrimination did not prevent Dr. Regardie from carefully analyzing and criticizing the methods and procedures of the Order and revealing the true character of its members.

With a new preface by Lon Milo DuQuette, author of Ask Baba-Lon, Answers to Questions of Life and Magick"
