Richard Bandler & John Grinder - Patterns of the Hypnotic Techniques of Milton H. Erickson, MD: Volume 1

Of Volume I, Dr. Erickson wrote, "Although this NLP book by Richard Bandler and John Grinder, to which I am contributing this Preface, is far from being a complete description of my methodolgies (as they clearly state), it is a much better explanation of how I work than I myself can give."
 

In short, the authors have formalized hypnosis in such a way as to open the door for medical, clinical, dental, and research uses of the vast potential of hypnosis.
