My continued reading on the subject of Ericksonian hypnotherapy has often taken me over the same familiar territory. It's a good territory, and there's no denying the satisfaction of having my opinions validated by more experienced heads, but Hypnotic Realities took me a step above that.
Erickson and Rossi's analysis of how Erickson approached hypnosis, language, calibration, and the unique individuality of every hypnotic subject managed to strike me as fresh and new, even after I'd consumed dozens of books on the subject, and taught me delightful new ideas on almost every page. If you're learning hypnosis and/or NLP, this is a valuable book to read and absorb and make your own.
This book was written before (but published after) Patterns of the Hypnotic Techniques of Milton H. Erickson, M.D., so the linguistic insights explored by Bandler and Grinder in Patterns will form a good background for appreciating Hypnotic Realities even more in light of what those volumes added to the understanding of Erickson's work.
