The first thing is, thirteenth verse, tapasa, "by austerity."
- tapasā brahmacaryena
- śamena ca damena ca
- tyāgena satya-śaucābhyāṁ
- yamena niyamena vā
- (SB 6.1.13)
- deha-vāg-buddhijaṁ dhīrā
- dharmajñāḥ śraddhayānvitāḥ
- kṣipanty aghaṁ mahad api
- veṇu-gulmam ivānalaḥ
- (SB 6.1.14)
These are the different steps, how one person can become civilized. So first thing is tapasā. Tapasā brahmacaryena (SB 6.1.13), austerities. Therefore in the Vedic civilization the children, they are taught from the very beginning brahmacarya, tapasā brahmacarya. A small boy, five-years-old boy . . . That is gurukula. Brahmacārī guru-kule vasan dānto guror hitam (SB 7.12.1). This is a way of life, to teach the brahmacarya, brahmacarya, celibacy, to restrain from sex life. That is brahmacarya.
So this is the beginning of civilization. The unlimited, unrestricted sex life like hogs and dogs, that is not civilization. Civilization, the first of all, to learn how to observe celibacy, to come to the point: no sex life. That is perfect civilization: no sex life. Therefore in the Vedic civilization you'll find the human society is divided into four orders and four spiritual orders, material and spiritual, varṇāśrama. Varṇa and āśrama. Brāhmaṇa, kṣatriya, vaiśya, śūdra, brahmacārī, gṛhastha, vānaprastha, sannyāsa. (break) Sannyāsa means, vānaprastha means, no more sex life. Brahmacārī means no sex life. So out of these four divisions of spiritual life, three divisions no sex life. Brahmacārī, gṛhastha, vānaprastha and sannyāsa.
Brahmacārī is taught from childhood how to keep brahmacārī, brahmacarya. This is the . . . Anyone who is taught from the beginning of life, "No sex life," then at young age he can control. If you still one cannot control, that . . ., this gṛhastha life is a concession for sex life. Actually, sex life is not required for advancement of civilization. That is advancement. Why? That if so long we are attached to sex life, we have to remain within this material world—in any form. There are eight million four hundred . . . Puṁsaḥ striyā mithunī-bhāvam etaṁ (SB 5.5.8). This is . . . Material world means sex desire. So if one wants to become fit candidate for going back home, back to . . .: no more sex life. That is civilization.
