In this seminal contribution to Transpersonal theory, Washburn describes the trajectory of the ego over the course of a lifetime. How does the ego develop from the Dynamic Ground, or Source of all psychic energy? Why is it necessary for the ego to forcefully separate itself from the Ground? What happens when some people are lucky enough to encounter "Regression in the Service of Transcendence"?

The book is a useful guide for the seeker encountering rough spiritual terrain as well as for the individual desiring a ego development model, which goes beyond what traditional psychology can offer.
