Alberto Villoldo, Ph.D., is a Cuban-born psychologist, medical anthropologist and author, writing primarily in the field of neo-shamanism. One day in his biology laboratory, Alberto realized that his investigation had to get bigger instead of smaller; Alberto needed to find a system larger than the neural networks of the brain. The microscope was the wrong instrument to answer the questions he was asking. Many others were already studying the hardware – Alberto Villoldo wanted to learn to re-program the SYSTEM. Anthropological stories hinted that there were people around the globe who claimed to know such things, including the Inka in Peru, the few remaining “shamans” in today’s modern civilization.
