Query: Godsend!

I purchased this book and the CD (separately sold) for my wife who was having surgery. We read the book and she listened to the cd. This book is fantastic and empowering! It gave her a sense of control over the procedure and made her part of the outcome. When she met with the surgeon and anaesthesiologist she was able to ask questions, request that they allow her to listen to the CD and asked that they talk to her during the operation.The author's mastery of healing techniques, of using the power within all of us to heal is outstanding!
