Following on from his first book - The Art of Hypnosis, this book covers more of the therapeutic aspects of hypnosis, using the skills of his mentor Charles Tebbetts. Again as with his first volume this is laid out in an easy to follow lecture style. This book is written and aimed at those who are studying the therapeutic aspects of hypnosis and in places gets quite technical if you have not got some understanding of hypnotherapy and its tools. A good self study guide that can be used alongside a training course.
