This book (Volume I) is worth reading by anyone interested in hypnosis. The authors present the major linguistic techniques that Erickson used to induce and maintain hypnosis, as well as his methods of doing hypnotherapy. They approach Erickson from the discipline of linguistics, so the reading is a bit technical at times, but perfectly understandable if you stick with it. They review the same material many times to make it very clear to the reader.(text cited from www.amazon.com)
