Hypnosis is a natural state of consciousness that with skillful guidance can be used productively by the population at large. Objectively, it involves moving the brain-wave activity down from wide awake (Beta) to that area half-way between being asleep and awake (Alpha and Theta). Subjectively, it involves narrowing down the focus of attention to one thing and redirecting the critical mind temporarily disabling normal filters.
Bright, creative, flexible people seem to make the best subjects. However, almost anyone can be hypnotized given a desire to enter an altered state and a willingness to participate.
From a therapeutic perspective, hypnosis can be used to add something to a person’s life, remove something from it, or release a person from binding fears so that he may express his true self.
