In the system of varnasrama-dharma, which is the beginning of actual human life, small boys after five years of age are sent to become brahmacari at the guru's asrama where these things are systematically taught to boys, be they king's sons or sons of ordinary citizens. The training was compulsory not only to create good citizens of the state, but also to prepare the boy's future life for spiritual realization.
The irresponsible life of sense enjoyment was unknown to the children of the followers of the varnasrama system. The boy was even injected with spiritual acumen before being placed by the father in the womb of the mother. Both the father and the mother were responsible for the boy's success in being liberated from the material bondage. That is the process of successful family planning.
It is to beget children for complete perfection. Without being self-controlled, without being disciplinary and without being fully obedient, no one can become successful in following the instructions of the spiritual master, and without doing so, no one is able to go back to Godhead. SB 1.5.24
