It is said in the Bhagavad-gita that out of thousands of men, only one takes an interest in the perfection of human life. The perfection of human life is to develop one’s dormant love for God, and thus be released from the terrible cycle of birth and death. People are so foolish that they simply waste time in temporary pursuits of material happiness, eating, sleeping, defending and enjoying sex life. Especially sex life. The sum and substance of material life is attraction for the opposite sex. The sum and substance of spiritual life is attraction to Krishna.
From Srila Prabhupada’s letter to Bhakta Steven Knapp – Bombay 18 December, 1975
