I read my first book on Enochian Magic in 1992, the first work by the Schuelers. Since then I have always kept myself up to date on publications on this topic, and I can without hesitation admire Bill Duvendack's efforts in his series of writings on the subject. My good friend Bill here combines in a very elegant way detailed knowledge about the history and practice of Enochian Magic with a deep look at its fundamentals, helping the reader to realize the transcendent power that lies behind the cultural veneer through which this magical system has been received.
