Our this material society means chewing the chewed. A father gives education to his son to earning livelihood, gets him married and settles him, but he knows that "This kind of business, earning money and marrying, begetting children, I have done, but I am not satisfied. So why I am engaging my son in this business?" This is called chewing the chewed. Chewing the same thing. "I have not been satisfied with this business, but why I am engaging my son also?" The real father is he who does not allow his son to taste the chewing the chewed. That is real father. Pitā na sa syāj jananī na sā syāt, na mocayed yaḥ samupeta-mṛtyum (SB 5.5.18). This is real contraceptive. A father . . . a man should not desire to become a father, a woman should not desire to become a mother, unless they are fit to save the children from the impending clutches of death. That is the duty of father and mother.
And how one can be saved? The saved means if the father and mother together gives education to the son about Kṛṣṇa consciousness, then he can be saved. The father's, mother's duty is . . . the same, apavarga-vartmani. Apavarga-vartmani: to give education in such a way that no more pavarga. No more pariśrama, no more phena, no more bhaya, no more vyarthatā, no more maraṇa. That is called apavarga-vardhanam. This is here real human life—human society cultivating knowledge in such a way that apavarga-vardhanam, gradually we are going forward for liberation. That is human civilization. Otherwise it is cats' and dogs' civilization. The same thing: punaḥ punaś carvita-carvaṇānām (SB 7.5.30). Again eating, mating, sleeping . . . that's all. Fearing and dying. This is general process. Āhāra-nidrā-bhaya-maithunaṁ ca. Eating, sleeping and sex life, and defending and dying. So this is . . . under these regulations the dogs and cats are there.
