This is one of the most valuable spiritual books that I have read in some time. The authors connect two of my primary topics of deep life interest- shamanism and the path of the magus in the Hermetic tradition. I mean, I've always sensed the connection, but I've encountered others that just didn't seem to get it. The authors make this connection- primarily through the classical mystery tradition of the western world. It is identified that the Hermetic tradition cannot exist without the foundation of the native shamanic tradition, while the shamanic tradition cannot progress without the projection of the Hermetic. One represents the roots, and the other the branches, of the Great Tree.
It was truly remarkable how page after page tied together my own interests, studies, and intuitions- it was almost like one long experience of high-level synchronicity. Of course, the forward and high praise by Gareth Knight should be enough to convince most knowledgeable readers that this book is the real thing.
You could do far worse than to make this book both your introduction, as well as, your primary text for the study of deep, intuitive, Gnostic, spirituality. I know that this book will be going into my permanent reference collection.
