…The perfection of human life is attained by following three principles of civilization: protecting the cows, maintaining the brahminical culture and, above all, becoming a pure devotee of the Lord. Without becoming a devotee of the Lord, one cannot perfect one’s human life. The perfection of human life is to be elevated to the spiritual world, where there is no birth, no death, no disease and no old age. That is the highest perfectional aim of human life. Without this aim, any amount of material advancement in so-called comforts can only bring the defeat of the human form of life. (from purport SB 3.3.28)
