Founded upon a revolutionary premise—providing a shortcut to initiation—Louis T. Culling's original edition of this classic ceremonial magick book broke all the rules. Llewellyn is proud to present an updated and expanded edition of this pioneering work. The G...B...G... or "Great Brotherhood of God" was an occult order founded by acclaimed magician Frater Genesthai. Louis T. Culling, one of the initial members of the G...B...G... in California, was instructed by Genesthai to reveal the Order's magickal curriculum when the time was right. Carl Llewellyn Weschcke, publisher of Culling's original edition of this book, offers illuminating commentary, definitions, and discussion points to render these profound magickal philosophies and practices more accessible and relevant for contemporary magicians.
