As a child, author Ray Rizzo suffered a head injury, and at seventeen, he began to study yoga to help alleviate the chronic symptoms caused by the injury. In his own recovery, he discovered an ability to assist others in their healing processes—a quest that would culminate in a shamanic apprenticeship deep in the Amazon jungle. After nearly a month of isolation there and using his years of experience in the healing arts, he developed his unique synthesis, which he shares in his book, Weightlessness.
