Sad-ācāra, just like we are teaching sad-ācāra, rise early in the morning, take your bath, change your cloth, wash your mouth, and then go to the Deity room and have maṅgala ārotika, then study, so many, so many, simply sad-ācāra. Sad-ācāra means . . . sat means "that will exist," and ācāra means "behavior." Sad-ācāra. So here it is said that Ajāmila, he became the husband of a prostitute. It is not the śāstric injunction. You can become husband, but not the husband of a prostitute. Then your life is finished. Naṣṭa sad-ācāra. You will be lost all . . . (indistinct) . . . therefore so much stress is given that wife should be chaste and the husband should be very well behaved, then life will be successful. Arjuna argued with Kṛṣṇa that "You're asking me to kill my brothers and relatives on the other side, so don't You think that if I kill them, their wives will be widowed and they will be polluted? And as soon as they will be polluted, there will be varṇa-saṅkara." Varṇa-saṅkara, the practical example of varṇa-saṅkara is the hippie in your country: no caste, no creed, neither useful for the material world, neither useful for the spiritual. That is called varṇa-saṅkara. Then he said, "My . . ." Arjuna . . . strīṣu duṣṭāsu varṇa-saṅkara virabhyati (BG 1.40): "My dear Kṛṣṇa, You are asking me to kill my . . . there will be widow, and they will be polluted, and there will be varṇa-saṅkara, and what is the loss? And when there'll be varṇa-saṅkara, then the whole world will be hell. It will be no more suitable for habitation of gentlemen. Finished."
Therefore in the Vedic civilization two things are very much stressed: to teach the man from childhood how to become expert in sad-ācāra, and woman trained up how to become chaste. So this chaste woman and this sad-ācāra, brāhmaṇa—ideal is brāhmaṇa —if they combine then there will be peace, there will be progress, there will be peace in the society, peace in the family. There is a poetry in English, "Society, friendship and love, divinely bestowed upon you." But that society is not this society. If we become husband of the prostitute, no, that is not possible. Then sad-ācāra will be finished. Nāmnā sad-ācāra. Dāsyāḥ saṁsarga-dūṣitaḥ (SB 6.1.21): as soon as you become associated with prostitute, then everything will be lost. Sad-ācāra lost means your progress in spiritual life is lost. Therefore we are stressing so much on the four points: no illicit sex, no meat-eating, no intoxication, no gambling. This is the way. If you are serious . . . but if you take it as a fashion, that is another thing. But if you take it seriously, to progress, then these things should be done. This is the basic principle of spiritual progress.
