A person who is trained in Krsna consciousness from childhood naturally becomes disinclined toward the material way of life, and at the age of fifty he gives it up. How does he start giving it up? The husband and wife leave home and travel together on pilgrimage. If from twenty-five to fifty one remains in family life, one should have some grown-up children. So at age fifty the husband entrusts the family affairs to some of his sons who are family men, and he and his wife go on pilgrimage to the holy places in order to forget family attachments. When the gentleman is completely matured in detachment, he asks his wife to go home to their children, and he remains alone. That is the Vedic system. We have to give ourselves a chance to progress in spiritual life, step by step. Otherwise, if we remain attached to material consciousness throughout all our days, we will not perfect our Krsna consciousness, and we shall miss the opportunity of this human form of life.
