There was lots of controversy over the Carlos Castaneda books and this one was the first. It is a very easy and conversational read about a personal account of working with a shape shifting shaman. Regardless of the verifiability of what Castaneda speaks of, there are
valuable teachings in this book. But keep in mind, no one is ever going to learn shamanism from a book. If you ever meet a shaman, I pray that you are well-read enough to have the good sense to forget everything you’ve ever read and shut up and listen.
And I pray that shaman is working for the good of ALL our relations.
