Still reading. From what I have read so far and what I have been told, this really is the definitive basis and should be in the knowledge base and library of any serious student of this subject. I have read most of the newer important writings and I still am finding this to be quite worthy of my time. If you are on the fence, I recommend waiting for a decent deal and then making the purchase.
Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
