This textbook covers fundamental discoveries about the biological basis for spiritual and shamanic states, transpersonal experiences, and consciousness itself. Derived from explorations into the very earliest prenatal development, this book describes how consciousness is based on biology inside the cell.With this theoretical foundation, we can now understand what traditional spiritual and shamanic practices do at a biological level, as well as understand what makes different healing therapies effective. More important are the very practical applications entirely new techniques for spiritual growth and healing become possible, through a synthesis of traditional concepts with modern microbiology.

This textbook on the theory of peak states and the biology of consciousness is used in our therapist training classes. Although it is written for professionals, weve made it available for laypeople that are interested in the cutting edge of consciousness research and its applications to psychology and medicine.
