At this stage a man is not a man but becomes an animal. Sex is after all an animal instinct. When mind stops motivating man, he is reduced to the state of an animal. In the Holy Scriptures of the most of the major religions of the world, there is an emphasis on correctness of behavior. Unfortunately in today's mundane world the emphasis on rectitude has been given a go by.
Man is consumed by consumerism.
When the glitter attracts a man, he goes all out to get it even if it is not Gold. That is where he falls in the trap of Mammon. That is where he goes away from God, and Satan gets him. Abstinence from sex, abstinence from junk food, abstinence from alcoholic drinks, abstinence from desire to acquire what does not belong to you, abstinence from reading, writing or thinking of sex and nothing but sex, abstinence from consuming stimulants which take you away from righteousness is Brahmacharya. It is a Vedic word, a product of Vedic philosophy of life, which all Aryas are enjoined to practice and then preach.
