This theme underlies every principle taught in the Sexual Purity course. Swami Sivananda in his book titled Brahmacarya writes:
“According to Yogic science, semen exists in a subtle form throughout the whole body. It is found in a subtle state in all the cells of the body. It is withdrawn and elaborated into a gross form in the sexual organ under the influence of the sexual will and sexual excitement. An Urdhvareta Yogi not only converts the semen into Ojas, but checks through his Yogic power, through purity in thought, word and deed, the very formation of semen by the secretory cells of the testes or seeds. This is a great secret. Allopaths believe that even in an Urdhvareta Yogi, the formation of semen goes on incessantly and that the fluid is reabsorbed into the blood. This is a mistake. They do not understand the inner Yogic secrets and mysteries. They are in the dark. Their Drishti or vision is concerned with the gross things of the universe. The Yogi penetrates into the subtle hidden nature of things through Yogic Chakshu or the inner vision of wisdom. The Yogi gets control over the astral nature of semen and thereby prevents the formation of the very fluid itself.”
When a man becomes sexually agitated, drops of semen are found in his urine. We hear in the Bhagavatam of men who discharged semen upon seeing an extraordinarily beautiful woman. So the more we can do to protect ourselves from doing and thinking of anything sexually stimulating, the easier our battle to achieve sexual purity will be. In other words, we often make it difficult on ourselves to be sexually pure by allowing sexual stimuli into our lives. You are not only what you eat, you are what you see, hear, feel, smell and ultimately you are what you think.
Are there ways you allow sexual stimulus into your life that you could easily avoid? If so, what are they?
