If you can conceive of hypnosis as a spectrum of awareness that stretches from waking to sleep, you will realize that some aspects are close to the waking state, and share the phenomena of waking; and some aspects are close to sleep, and participate in the phenomena of light sleep. But over the entire spectrum , suggestibility is increased; and this is what makes hypnosis potentially beneficial, provided we put the suggestibility to a constructive use. The depth of hypnosis does not always correlate with the degree of suggestibility . In other words, even if you go no deeper than the lightest stages of hypnosis and are merely mildly relaxed, you will still be able to benefit from its therapeutic effects. It so happens that with practice you should be able to go deeper , but this really is not too important in the great majority of cases .
