In his third book, the author of Spiritwalker and Medicinemaker illuminates the emergence of a modern Western shamanism, revealing what it means to him as a scientist to be also a mystic and a medicine man in this age of technology and science. His connections with kahuna initiate Nainoa give us an intimate look into native Hawaiian spiritual wisdom, and their amazing visionary voyages together finally bring them face to face with each other and the mysterious Source of all existence.
