According to Vedic civilization, procreation should not be contrary to religious principles, and then the birthrate will be controlled. As stated in Bhagavad-gita (7.11), dharmaviruddho bhutesu kamosmi: sex not contrary to religious principles is a representation of the Supreme Lord. People should be educated in how to give birth to good children through samskaras, beginning with the garbhadhana-samskara; birth should not be controlled by artificial means, for this will lead to a civilization of animals. If one follows religious principles, he automatically practices birth control because if one is spiritually educated he knows that the after-effects of sex are various types of misery (bahu-duhkha-bhaja). One who is spiritually advanced does not indulge in uncontrolled sex. Therefore, instead of being forced to refrain from sex or refrain from giving birth to many children, people should be spiritually educated, and then birth control will automatically follow.

If one is determined to make spiritual advancement, he will not beget a child unless able to make that child a devotee. As stated in Srimad-Bhagavatam (5.5.18), pita na sa syat: one should not become a father unless one is able to protect his child from mrtyu, the path of birth and death. But where is there education about this? A responsible father never begets children like cats and dogs. Instead of being encouraged to adopt artificial means of birth control, people should be educated in Krsna consciousness because only then will they understand their responsibility to their children. If one can beget children who will be devotees and be taught to turn aside from the path of birth and death (mrtyu-samsara-vartmani), there is no need of birth control. Rather, one should be encouraged to beget children. Artificial means of birth control have no value. Whether one begets children or does not, a population of men who are like cats and dogs will never make human society happy. It is therefore necessary for people to be educated spiritually so that instead of begetting children like cats and dogs, they will undergo austerities to produce devotees. This will make their lives successful.
