Veerya, the vital fluid or semen, is life. You can attain eternal bliss and peace by preserving the Veerya. Brahmacharya [celibacy] means control of the Veerya. The vital force or Veerya is preserved only by one who is established in the practice of Brahmacharya. The vital fluid or semen is lost and wasted during sexual indulgence.
From food comes juice or chyle; from chyle comes blood and flesh; from flesh comes fat; from fat comes bones; from bones come marrow. Lastly, from marrow comes semen. The Veerya comes out of the very marrow concealed in the bones. It is found in a subtle state in all the cells of the body. Mark here how precious the semen is! It is the last essence of food. It is the essence of essences.
As the vital force is the most precious substance in the physical body, it should be carefully preserved. Its wastage means loss of physical and mental energy.
It is said that a drop of semen comes out of forty drops of blood. According to Ayurveda it comes from eighty drops of blood.
Just a sugar pervades the entire sugarcane, and butter pervades milk, so also semen pervades the whole body. Just as buttermilk is thinned after the butter has been extracted, so also the semen is thinned by its wastage. The more the wastage of the semen, the more the physical and mental weakness.
When semen is preserved, it gets reabsorbed by the body, and stored in the brain as Ojas Shakti or spiritual power. The seminal energy is changed into spiritual energy. This is called the process of sex-sublimation. The Ojas Shakti is used for spiritual Sadhana by the Yogi.
The vital force is closely linked with the nervous system. Hence, it is vitally necessary to preserve it carefully if one desires to have strong nerves.
The semen is the real vitality in man. It is the hidden treasure in him. It gives a glow to the face, strength to the intellect and well being to the entire system. Girls, too, suffer great loss through having unchaste thoughts and giving way to lust. Vital nervous energy is lost. There is a corresponding loss of Veerya in them as well.
The Srutis state that a man’s full life span is a hundred years. This can be achieved only if a person is established in perfect Brahmacharya. It is through the attainment of good conduct only that one can live to a ripe old age and be ever happy and peaceful. Even if all other qualities may be lacking, good conduct alone will ensure longevity.
You must have pure character, otherwise you will lose your vital energy or Veerya. An early death will be the result.
Another important point to remember is that the secret of long life lies in the choice of pure food and drink, chastity, temperance, sobriety and a cheerful and optimistic outlook on life. So, gluttons, drunkards and those given to idleness and laziness, cannot hope to have long life.
According to psychological and natural laws, the length of human life, or any life, should be at least five times the period necessary to reach full growth. The horse grows for a period of about three years and lives to be about twelve or fourteen. The camel grows for eight years and lives to be forty. Man grows for about twenty to twenty-five years. If all accidents are counted out, his normal duration of life should be not less than one hundred years.
