This world, what is this world, material world? The material means sex desire. That's all. The woman is hunting after man, and the man is hunting after woman. Either in human society or bird society or beast society or dog society or cat society, the principle is sex. And the human society means to understand it, that what is the basic principle of material life. If we understand it is sex, therefore we have to cut down the sex desire gradually by becoming brahmacārī, gṛhastha, vānaprastha, sannyāsa. This is the process. Otherwise, if I do not know what is the cause of my material bondage, then how we can take remedy? This is the cause, puṁsaḥ striyā mithunī-bhāvam etam. The desire is there. As soon as one is grown up, reaching youthful time, the sex desire is very strong, very strong. So they unite. A man, a boy finds out a girl; a girl finds out a boy. They unite, and there is sex, and as soon as there is sex then there is bondage. Immediately. Puṁsaḥ striyā mithunī-bhāvam etaṁ tayor mitha. As soon as they unite, then the relation becomes very tight, very strong. Then, as soon as one is married, or unmarried—generally speaking married—then he wants apartment. Ato gṛha. Gṛha means apartment. So long he remains brahmacārī there is no need of apartment. He can dine right out on the street. (laughter) But as soon as they're joined together, immediately apartment, gṛha. Then how to maintain the apartment? Then he must have land. Because formerly there was no industry; everyone must produce his own food by tilling the field. So to produce food he must have some land. So land was available, is still available. One can produce. But they have left that process of livelihood. They are taking to industry.
So ato gṛha. First of all apartment, then kṣetra. Kṣetra means agricultural land. Then some capital. Ato gṛha-kṣetra. Then as soon as they're married they, at least woman, wants some child, children. Ato gṛha-kṣetra-suta-āpta. If he has got very nice apartment and good condition of living, then he'll invite some friends, "Please come and see I am happily living." (laughter) And one after one—bondage. One after another. Because if you're opulent, you have to show your friends. Otherwise what is your opulence? If your friends do not come and say, "Oh, you're so wonderful. (laughter) Yes. You have got such a nice wife, nice apartment. Wonderful." Because in the Kali-yuga this is wonderful. Everything is mentioned in śāstra. Dakṣyaṁ kuṭumba-bharaṇam (SB 12.2.6). If one can maintain one wife and some children, ah, he's most expert. (laughs) Forget Kṛṣṇa. Here is expert. (laughter) Dakṣa. Dakṣa means expert: "Oh, he's expert. How he's maintaining." When I first came, I met one elderly lady. She had a son. So, as Indian I asked, "Oh, why don't you get your son married?" She replied, "Oh, I have no objection. If he can maintain a wife I have no objection." That means to maintain a wife is a very big job in your country. I've seen it. (laughter) Of course, when we talk, we must talk freely, what is the fact. (laughter) But formerly, in our father's age, they used to come to foreign countries and they thought it, it is a great laugh to possess one white wife. Yes, they are thinking like that. So all the students who used to come to England for higher studies, naturally he would carry one white elephant. (laughter) They used to say—it is not my coined words—they used to say, "Oh, to maintain European wife, it is maintaining white elephant." So anyway, you have got so many white elephants. (laughter)
So this is the way, ato gṛha-kṣetra-suta-āpta, friends. Arjuna was lamenting, "My dear Kṛṣṇa, You are asking me to fight with my relatives. Then suppose I become victorious and they're killed. Then whom I shall show the kingdom?" That was his objection. (laughter) "If everyone is killed on the other side, my friends and relatives, and suppose I become victorious, then whom I shall show my prosperity?" So āpta, suta, ato gṛha-kṣetra-suta-āpta and vitta, and money. So this, one after another. First wife, then apartment, then field for agriculture, then friends, then children, then money, bank balance. In this way he does not know he's becoming entangled more and more. Ato gṛha-kṣetra-suta-āpta-vittaiḥ, janasya moho 'yam (SB 5.5.8). He's thinking that "Now everything is settled up; I am very happy." (laughter) And next day death comes and kicks him out: "Get out!" That he does not understand. That he does not understand, that "Any moment death can come and kick me out of all this arrangement." That is ignorance. That is foolishness.
