The unprecedented sale of _The Power of Positive Thinking_ by Norman Vincent Peale and other inspirational literature proves that millions of modern people recognize the efficacy of constructive thoughts. What most of them do not recognize is that they are capable of implanting these beneficial thoughts in their own minds without reference to any outside agencies. This can be done through self-hypnosis. In modern society we have many cults, religions and methodologies which have mental discipline as their goal. The best example of a methodology is psychosomatic medicine which deals with the interrelationship of the mind and body in the production of mental or physical illness. The rapid growth of hypnosis in the last few years is another example, and it is gratifying to see that the emphasis in this field is now shifting from hetero-hypnosis to self-hypnosis. Self-hypnosis is a highly suggestible state wherein the individual can direct suggestions to himself. It is a powerful tool in any therapeutic process, and highly motivated subjects can parallel the success of hetero-hypnosis through their own efforts. Self-hypnosis can be used as a palliative agent and can even afford lasting results in many areas of the organism. Self-hypnosis can alleviate distressing symptoms, substitute strong responses for weak responses, help overcome bad habits, create good habits and help one's power of concentration. The total personality is eventually changed to the point where it can function adequately in an increasingly difficult environment. In learning self-hypnosis, the subject does not relinquish control of himself as is commonly believed. Actually, more control is gained. Self-sufficiency and self-confidence are inevitable results. It is well to remember, however, that even good things may be overdone, and good judgment is necessary for favorable results. Neither hypnosis nor self-hypnosis should ever be used indiscriminately. The effectiveness of self-hypnosis depends upon many factors. Strong motivation, intelligent application of suggestions and diligence are prerequisites. We are not suggesting that self-hypnosis can take the place of all forms of psychotherapy. We do recommend it as an adjunct to therapy when indicated. Used judiciously, it can contribute a great deal to the individual's physical and emotional well-being and happiness. As a professional hypnotist for many years, I have seen astounding and apparently miraculous results by individuals using self-hypnosis. Many of these cases seem unbelievable to those not familiar with hypnotic phenomena. It should be remembered, though, that many individuals seek hypnosis only when all other forms of therapy have failed. This is so common that hypnosis has come to be known as a port of last call. Yet, despite the seeming hopelessness of such cases, medical literature lists thousands of remarkable recoveries.
