Our first principle is to become Kṛṣṇa conscious, and other things, secondary. Putrārthe kriyate bhāryā. If you can produce nice children, Kṛṣṇa conscious children, it will, you will do greatest service to the human society. Because the human society is producing children like cats and dogs, the whole human society is in trouble. How you can expect peace and prosperity in the society of cats and dogs? Therefore there is necessity. There is necessity to produce children of Kṛṣṇa consciousness, to train them from the very beginning. You will be all glad to know that some of our students, very small boys in San Francisco, they are being trained, and they are making wonderful progress. So there is no fault of these hippie boys and girls. They have not been trained. Not only here, every part of the world, the educational system is not very satisfactory. From the very beginning of their life they are allowed to mix freely, and they are allowed to enjoy sex life unrestricted. This is neither good for their health nor for education. So therefore we are getting now the result of education: communists and hippies. So people, those who are guardians of the society, should take serious note of it and make life very regulated.
What is...? The necessities of this life is, because we have got this material body, we must eat, we must sleep, we must defend, and we must mate. These are the demands of this body. But they should be so regulated in Kṛṣṇa consciousness that it will not be disturbing element, but we shall make progress further and further towards spiritual realization of Kṛṣṇa consciousness. Therefore, not only the new bride and bridegroom, I request every one of my students who are present that this... The aim of married life is to produce nice children, Kṛṣṇa conscious children. That is the best service to the human society: produce nice children. Don't produce cats and dogs. That is my request. Otherwise don't produce. Remain separate. Separate means there is no separation, but don't produce children. That is my request. Putrārthe... Pitā na sa syāj jananī sā syāt. The Bhāgavata says, "One should not become a father, one should not become a mother, unless they are able to protect the children from the imminent danger of death." What is that? The cycle of birth and death. If you can train your children to Kṛṣṇa consciousness, then your child will go back to Godhead in this life. That should be the aim. As you will try to go back to Godhead in this life, similarly, you shall take charge of your children that he can also go in this life back to Godhead. The mother's and father's duty should be that "This child is born out of my womb, and this is the last phase of his life, to come into this womb of any animal or man—no more material body." That should be the responsibility of father and mother. That is the direction of Bhāgavata.
