Shamanism is a method and system for healing that is many thousands of years old. Found across the globe in remote cultures and now in urban environments shamanism is alive and functioning well. Contemporary, traditional and Core shamanic studies are available throughout many regions of the world through individually trained teachers and practitioners and indigenous shamans. For Core shamanic studies, the Foundation for Shamanic Studies founded by Michael Harner offers weekend and long term programs and training workshop.
There are many books, journals and blogs available on shamanism some of my favorites will be listed on this site
