The authors provide an overview of the fascinating field of hypnosis, starting with Milton Erickson's indirect-permissive hypnosis style and moving to George Eastbrook's direct-authoritarian style. All techniques share the commonality of enabling a connection to the unconscious. Trance states are the secret to the positive effects of hypnosis. Therefore, a focus of the book is on how to evoke phenomena that are signs of deep trance states. What is exceptional about this book is how deeply and comprehensively the topic is presented. Tad has studied the development of hypnosis from its beginnings to the master hypnotists of the 20th century. The book documents Tad's ability to distill complex concepts to their essence, making them more understandable, relatable, and easier to apply. - David Shepard.
