The attainment of self-hypnosis can be an intricate and elusive procedure as I have already pointed out. The purpose of the entire book is to instruct, point out and give you the necessary understanding and knowledge required to achieve this end. Without this understanding, this can become a very frustrating effort. It is hoped that by understanding and being aware of some of the ramifications of hypnosis, you will be able to achieve your goal in the quickest possible time. It should also be pointed out that no two subjects react in the same way and that different methods and requirements are necessary to suit the individual. It is a mistake to try to make the subject adhere to a rigid methodology. The greater flexibility of the hypnotic procedures, the greater the chance for success. Let me, at this time, further discuss some of the hypnotic aids that are used in the induction of hypnosis. We have already discussed the use of the hypnodisc and crystal ball and chain. The same principles are involved in any other object which is used as a means of fixation or of tiring the eyes. Hypnotic phonograph records and hypnotic tape recordings represent new devices that have been instrumental in conditioning subjects for self-hypnosis. The subject plays the record or tape on his phonograph or tape recorder and is conditioned over a period of time to respond to hypnosis at a given signal or phrase. He, in turn, can change this key phrase to one of his own choosing. Should you own or have access to a tape recorder, I would suggest recording an induction of hypnosis and playing it back to yourself in this manner as though you were hypnotizing someone else. I have produced three different hypnotic records and a 30-minute hypnotic tape containing the three records which are sold commercially. One record, called the Musical Hypnotic Record, has a very pleasant, relaxing musical background as the voice of the hypnotist induces hypnosis. The second record, called the Metronome Hypnotic Record, incorporates the monotonous and lulling beat of an electric metronome in the background. The subject is instructed to mentally repeat "sleep" as he slowly inhales and "deep sleep" as he slowly exhales in rhythm with the beat of the metronome. While the subject is concentrating on this activity, the voice of the hypnotist induces hypnosis. The third record, called Self-Hypnosis Record No. 3, contains only the voice of the hypnotist inducing hypnosis. It features a unique approach and technique.
