Shamans are probably the least understood group under the umbrella term I'll call "New Age" (meaning wiccans, pagans, psychics, shamans,etc.) I say this because people are skeptical of psychics, hateful/fearful of witches (pagans, Wiccans, etc.) But it seems like the only thing people know about shamans is from TV. Let's see: probably Native American, feathers, burn sage and stuff, do drugs and enter trance-like states in which they commune with spirits.
First of all, some of this stuff is false, and there is so much more to shamanism. It is a very interesting belief system (I won't call it a religion since some people feel it is and others don't). Shamanic sects exist all around the world, and they are all very different.
This isn't a great introduction to shamanism and it is actually pretty boring. I found it organized very poorly, there is seemingly no structure. The author does not present a diverse look at shamans around the world, he mostly focuses on one part of the world (South America, so if you're into that, the book talks about it a lot). A lot of it felt like a memoir and the author himself has only studied shamansm, I don't think he is an actual shaman. He gets off topic pretty frequently. Like one time, he starts talking about how he had sex with a native woman while visiting a shaman. What?
So I wouldn't call this a beginner's shamanism book. It is more of a book about shamanism and various perspectives on shamanic practices. Pretty disappointing, I have to say.
