In 1985, anthropologist Hank Wesselman began to experience disturbingly vivid altered states that ultimately propelled him on 12 fantastic journeys across time and space. He wrote about these in Spiritwalker. Now Dr. Wesselman continues his extraordinary narrative as he recounts his true adventures where he is given foreshadowings of imminent ecological, political, and spiritual challenges to the future of civilization. Dr. Wesselman learns that his journeys are much like the journeys shamans of all cultures have taken for years. But his journeys take him far into the future, past the collapse of civilization, to a "new" stone age. There he meets a Hawaiian Kahuna mystic named Nainoa who teaches the author about what the world is like after the fall of the modern age. The result is another fascinating adventure, an exciting discovery, and the story of how a hardheaded scientific realist may have stumbled on an important piece in the puzzle of human evolution.
