My first experience hearing about shamanism was in a class I was taking on alternative healing in 1972 at the University of California in San Diego. Our distinguished guest was Dr. Andrew Weil. Dr. Weil had just returned from the Amazon jungle where he traveled to Huautla de Jimenez , gathering information about medicinal plants and healing. That trip turned out to be more than a plant gathering experience for the young Dr. from Harvard. I was mesmerized as he talked about his experiences with the shamans of the region.
