If you are trained in Craniosacral Therapy, especially under Upledger's model, this book is for you! If you found Upledger's book a bit dry or difficult to plod through and not an easy resource or want more information ont how CST and restrictions relate to all of the organ sytems,glands,tissues and diseases this book is a must have. It is very,very informative and difficult medical concepts are broken down to an understandable level. It made the lightulbs go off in my head. Once you can feel the CS pulse you can use this book to learn how to heal more than you ever imagined. You do not need the first volume,if you are already a CST. If you are not, but are any type of energy practioner the first volume would be a good resource to have, but this second volume can stand alone. I love this book.It is well worth every penny it costs!
