This is the masterful biography of the Magus Aleister Crowley, written by the one person most qualified to write it. Israel Regardie was a friend and student of Crowley's, and served as his personal secretary for some time. In this book, Regardie manages to write a fair and balanced view of Crowley. It is an intelligent and insightful look into Crowley's life, Magick and Mysticism. Dr. Regardie interprets all this from the wisdom of experience. A member of the Golden Dawn, O.T.O. and A.A., Regardie writes with deep insight and compassion, openly revealing his own feelings, and thus providing a unique insight into Crowley. This book is the classic biography of Crowley. This is the second New Falcon edition of the book (2014) edited with a Foreword by the Crowley scholar and Golden Dawn adept David Cherubim.
