It is the nature of people to try and pigeonhole this writing in some category or another. Several times though the book there is a warning against this. I my self see him as a hybrid of Jung and Catechism.
However I find this a revolutionary work that allows one to see the world in a new or ancient light. We have an opportunity to require or gain a perspective, a reality, a dimension that Thomas Moore calls soul. If nothing else reading the introduction will make this clear. I do not want to paraphrase Moore's works.
The book is well written and the layout is perfect to take you from ground zero of the process of Care of The Soul to a whole new life. However for me I felt a little like reading Dave Berry where he takes the normal and mundane and expands it beyond logic. You wonder how you got there.
He gets into interpreting dreams but not the standard stuff in other dream books. And shows how to relate tem to the topic of Care of The Soul. Somehow he bypasses a subject that I would be interested in. I use dreams to be more creative in work. Usually I can come up with unique solutions or insights in the middle of the night.
By the time you reach chapter eleven "Wedding Spirituality and Soul" you can see he is more into Jung than S. Freud. Also items that start to look like hypnosis byproducts ate creeping into the conversation.
Towards the end of the book he gets more concrete and wraps up lose ends.
Bottom line is you can not just read the book; you must live it to, to know it. And then again there is no guarantee.
