Soul initiation is an essential spiritual adventure that most of the world has forgotten -- or not yet discovered. Here, visionary ecopsychologist Bill Plotkin maps this journey, one that has not been previously illuminated in the contemporary Western world and yet is vital for the future of our species and our planet. Based on the experiences of thousands of people, this book provides phase-by-phase guidance for the descent to soul -- the dissolution of current identity; the encounter with the mythopoetic mysteries of soul; and the metamorphosis of the ego into a cocreator of life-enhancing culture. Plotkin illustrates each phase of this riveting and sometimes hazardous odyssey with fascinating stories from many people, including those he has guided. Throughout he weaves an in-depth exploration of Carl Jung's Red Book -- and an innovative framework for understanding it.
