There are many who think they are impotent but it is very rare that there is an impotent person. For him I really feel compassion -- because he has no energy to be trans-formed, no energy to be transformed with. Something is missing. He will never become that fragrance I call BRAHMACHARYA. He will miss that joy. He will miss that joy that comes through sex and he will miss that joy that comes by going beyond it. He is really pitiable.
But it is very rare. Out of a hundred impotent people ninety nine percent simply believe that they are impotent. Certain things may have caused their belief. Maybe they were too much against sex, too repressive. Repression has gone so deep in the system that it does not allow the system to feel sexuality. Their body has become disconnected with their energy. Then they become impotent. Or, they may be impotent because they go on living with a woman or a man with whom there is no love. Then by and by they start feeling there is no interest, it is all boring. The body does not respond any more. Many married people become impotent. It is marriage that creates impotence. And many repressed people become impotent. But these are false impotencies, they call be transformed, easily changed. And they should be changed before time is lost. One should live life in all its dimensions.
-Osho, “Zen: The Path of Paradox, Vol 1, #8, Q3”
The sex center functions through imagination. That is why even in dreams you can get erections and ejaculations. They are actual. Dreams are just imagination. It has been observed that every man, if physically fit, will have at least ten erections in the night. With every movement of the mind, with only a slight thought of sex, the erection will come. Your mind has many energies, many faculties, and one is will. But you cannot will sex. For sex will is impotent. If you try to love someone, you will feel you have gone impotent. So never try. Will never functions with sex; only imagination will function. Imagine, and the center will start to function. Why am I emphasizing this fact? Because if imagination helps the energy to move, then you can move it upwards or downwards just by imagination. You cannot move your blood by imagination; you cannot do anything else in the body by imagination. But sex energy can be moved by imagination. You can change its direction.
