This is a very good summary of Core Shamanism from the man who started it, Michael Harner, Ph.D., and should steer anyone interested in shamanism into the right direction. He is certainly the man who started it all for me. There are so many misconceptions out there in today's world about what shamanism is and what a shaman is. Here Michael touches on, among other details of the shamanic experience, the discipline involved in being a shaman and dispells the idea that taking mind altering substances helps to make you a shaman but rather the use of the drum rhythms actually drive the journey in most of the world. Michael is in his 82nd year in this video from his keynote address for the SAND (Science and Non Duality) Conference 2011, and his knowledge gained from experience and his quick sense of humor are still ever present with him.
