This book is an occult masterpiece, with deep esoteric meaning. It describes in detail how the mystery priesthoods did and still do function. Of course, a few things are "beefed up" magickally, much as Hollywood uses blue lightning effects when a wizard casts a spell. However, this book is a guide and a reminder to all practitioners of the occult sciences of where we came from, and where we're going, especially in our modern age where blindfolding an initiate is considered "terror". Recommended for advanced occult practitioners, only insomuch as that the information can be fully digested and understood by the more well-versed reader. For younger students, read it by all means, but don't forget to pick it up again twenty years from now, because it will unlock an entire new vista to the more experienced mind, which might better recognize the symbology found within.
