This book is an inquiry into ki-energy, its role within Eastern mind-body theory, and its implications for our contemporary Western understanding of the body. Yuasa examines the concept of ki-energy as it has been used in such areas as acupuncture, Buddhist and Taoist meditation, and the martial arts. To explain the achievement of mind-body oneness in these traditions he offers an innovative schematization of the lived body. His approach is interdisciplinary and cross-cultural, offering insights into Western philosophy, religion, medical science, depth psychology, parapsychology, theater, and physical education. To substantiate the relationship that ki-energy forms between the human body and its environment, Yuasa introduces contemporary scientific research on ki-energy in China and Japan, as well as evidence from acupuncture medicine and from the experience of meditators and martial arts practitioners. This evidence requires not only a rethinking of the living human body and of the mind-body and mind-matter relation, but also calls into question the adequacy of the existing scientific paradigm. Yuasa calls for an epistemological critique of modern science and explores the issue of the relation of teleology to science.
