The Stormy Search for the Self: A Guide to Personal Growth through Transformational Crisis
This is an interesting book. More from the point of view of assuring people who believe in alternative views of reality that they aren't necessarily insane just seeing the world in a different way. Also interesting in that Mr (actually Dr) Grof is a qualified psychologist and recognises that persons going through this kind of problem may be labeled as clinically suffering from some form of mental illness when that is not the treatment they need.
