While the repression of a memory is a psychological process, the suppression of feeling is accomplished by deadening a part of the body or reducing its motility so that feeling is diminished. The repression of the memory is dependent upon and related to the suppression of feeling, for as long as the feeling persists, the memory remains vivid. Suppression entails the development of chronic muscular tension in those areas of the body where the feeling would be experienced. In the case of sexual feeling, this tension is found in and about the abdomen and pelvis

~ Alexander Lowen

Since the experience is different for each individual, the tension will reflect that experience. In some persons the whole lower half of the body is relatively immobilized and held in a passive state; in others the muscular tensions are localized in the pelvic floor and around the genital apparatus. If the latter sort of tension is severe, it constitutes a functional castration; for, although the genitals operate normally, they are dissociated in feeling from the rest of the body. Any reduction of sexual feeling amounts to a psychological castration. Generally the person is unaware of these muscular tensions, but putting pressure upon the muscles in the attempt to release the tension is often experienced as very painful and frightening.

As adults, we hvae many inhibitions against crying. We feel it is an expression of weakness, or femininity or of childishness. The person who is afraid to cry is afraid of pleasure. This is because the person who is afraid to cry holds himself together rigidly so that he won't cry; that is, the rigid person is as afraid of pleasure as he is afraid to cry. In a situation of pleasure he will become anxious. As his tensions relax he will begin to tremble and shake, and he will attempt to control this trembling so as not to break down in tears. His anxiety is nothing more than the conflict between his desire to let go and his fear of letting go. This conflict will arise whenever the pleasure is strong enough to threaten his rigidity.Since rigidity develops as a means to block out painful sensations, the release of rigidity or the restoration of the natural motility of the body will bring these painful sensations to the fore. Somewhere in his unconscious the neurotic individual is aware that pleasure can evoke the repressed ghosts of the past. It could be that such a situation is responsible for the adage No pleasure without pain.

We must realize that we are all, like Dr. Faust, ready to accept the devil's inducements. The devil is in each one of us in the form of an ego that promises the fulfillment of desire on condition that we become subservient to its striving to dominate. The domination of the personality by the ego is a diabolical perversion of the nature of man. The ego was never intended to be the master of the body, but its loyal and obedient servant. The body, as opposed to the ego, desires pleasure, not power. Bodily pleasure is the source from which all our good feelings and good thinking stems. If the bodily pleasure of an individual is destroyed, he becomes an angry, frustrated, and hateful person. His thinking becomes distorted, and his creative potential is lost. He develops self-destructive attitudes.
