This book looks at the shamanic world to seek explanations for the healing and psychic powers displayed by shamans, in terms of quantum physics. Fred Alan Wolf is a physicist and popularizer of the New Science and author of "Taking the Quantum Leap" which won the American Book Award for Science in 1982. Throughout the remotest corners of the old and new worlds, the author visited shamans from many different traditions, recording their conversations and distilling from these experiences a vision of human potential.
