How a man becomes entangled in this material world, everything is described in the Śrīmad-Bhāgavatam. Puṁsaḥ striyā mithunī-bhāvam etam. This material world means sex attraction, mithunī-bhāva. The man is searching after woman, woman is searching after man. This is material life—in human life, in bird's, beast's . . . just these sparrows—they are trying to make some nest on this chandelier to enjoy sex and lay eggs. Therefore they require some place. The basic principle is sex. First of all sex life, then other necessities. First of all, seeing, man and woman. Then, when they unite, puṁsaḥ striyā mithunī-bhāvam etaṁ tayor mitho hṛdaya-granthim āhuḥ (SB 5.5.8). When they unite and they get children, then the hard knot of heart—"She is my wife. She's (He's) my husband. We cannot separate . . ." Hard knot. Hṛdaya-granthi. Already there is attraction. Now this attraction becomes more and more tight after unity. Then we require a place to live together, "Home, sweet home." Yes, very sweet. (chuckles) The whole day and night, work. And this is moha. He is working hard day and night. There is not a single's moment leisure, and still he's, "Sweet home." This is illusion.
So ataḥ gṛha. As soon as a man and woman or a male-female, either bird, beast or human being or demigods, everyone . . . then he requires home, gṛha, then land to produce food, gṛha-kṣetra, then children. Gṛha-kṣetra. Because when a man is married, the social life, if he has no children, that is means vacant home. Putra-hīnaṁ gṛhaṁ śūnyam. Cāṇakya Paṇḍita has said, vidyā hīnaṁ jīvanaṁ śūnyam: "One who is not educated, his life is zero." Vidyā hīnaṁ jīvanaṁ śūnyam. And diśaḥ śūnyā deha abāndhavāḥ: "And if you want to go to some foreign place, if that place is not a holy place . . ." Because according to Vedic system, they go on touring to see holy places, tīrtha-sthāna, or to a friend's house. "So if you are going to some foreign countries, if there is no friend and no devatā, then it is useless." Diśaḥ śūnyā deha abāndhavāḥ. Or putra-hīnaṁ gṛhaṁ śūnyam: "You are married, but you have no children. That is also vacant, zero." Putra-hīnaṁ gṛhaṁ śūnyam. Sarva-śūnyā daridratā: "But if you are poor, then everything is zero." Your vidyā is zero, your home is zero, and your friend is zero, because nobody will care you.
