It has been a long time since I read this book, because I was forced to give it away when I was backpacking - it's heavy. I would highly recommend it to people interested in healing, particularly the blend of Eastern teachings on the chakras and Western ideas on psychology. It is good for both understanding your own journey, and being a participant on the journey's of others.
This is not your typical New Age handbook. It's a textbook, and has a lot of detail to get through.
I have read very few books in this field that were more lucid or instructive.
