If you are interested in self-healing of ANY part of your person or are involved in the medical field, alternative medicine, hands on healing...etc, then buy this book! (Buy "Light Emerging" also!) Most books on healing using the human aura are flaky nonsense. In fact, most (not all) "New Age" books are nonsense in my opinion. This book is a strong exception. I honestly believe that this book will one day be considered a revolutionary text in modern medicine - that the techniques outlined in this text will one day become standard practices in modern medicine. I might add, I'm a very skeptical reader when it comes to non-traditional thought. I'm not some flake running around with crystals on my neck "sucking up bad energy." I'm a practicing mechanical engineer with a strong traditional educational background (incl. grad degree) in critical analysis. I should also mention I've attended one of her healing workshops and saw things that completely amazed me and also some things that seemed a bit odd. However, overall I would certainly recommend going to one of her workshops. If interested, you may wish to search for her web site under "Barbara Brennan School of Healing"
