Island of the Sun recounts the American psychologist Alberto Villoldo’s return to Peru in search of the Quechua Indian shaman Don Jicaram. The authors’ earlier book, Dance of the Four Winds, described Villoldo’s first initiation, under Don Jicaram, into the secrets of the Inca Medicine Wheel and the spiritual journey of the Four Winds. Villoldo had begun that journey in the South, where one goes to confront and shed the past. With use of the powerful mind-altering plant ayahuasca, he had continued to the West, a direction also inhabited by fear and death. Now in Island of the Sun he prepares himself for the journey to the North, where lies the wisdom of the ancient Inca shamans. Traveling from Machu Picchu to the Island of the Sun, a sacred site in Bolivia, Villoldo uncovers a profound secret about the journey to the East–the journey home.
