So how much rascal they are we must know. So therefore we should give up their company. Asat-saṅga-tyāga vaiṣṇava-ācāra. Otherwise, asat... Asat eka strī-saṅgī kṛṣṇa... There are strī-saṅga, vaidha-avaidha. Vaidha means regular, according to śāstra. According to śāstra means restricted. Śāstra restricts. Śāstra means śās-dhātu. Śās-dhātu means śāsana, ruling. From śās-dhātu, śāstra has come, śastra, weapon, has come. And śās-dhātu, from śās-dhātu, śiṣya also comes. These words are derived from śās-dhātu. Śāstra, śastra, śāsana. Śāsana means ruling. Sanskrit is very nice language. From one verbal root, you can manufacture so many words; therefore it is very difficult to make Sanskrit dictionary. It is very difficult. The so-called Sanskrit dictionaries available in the market, you won't find all the words. It is not possible. Because so many words are manufactured by one dhātu. How many they will add? But there is one book, what is the name of that book? Meaning, this word means this, this, this, that...?

Bhavānanda: No, that is the name for the book. Any book which gives so many different words, word meanings for one word, is called thesaurus.
Prabhupāda: So this śāstra, śāstra-vidhi. Śāstra-vidhi. Loke vyavāyāmiṣa-madya-sevā nityā hi jantoḥ. Nityā hi. Na hi tatra codanā. One does not require encouragement. One is not taught in the school how to learn sexual intercourse. No. These things are already there. Nitya, nityā hi jantoḥ. Every living entity has got these propensities: intoxication, sex intercourse. Vyavāya āmiṣa. Āmiṣa: meat-eating, fish eating. They're there already. One does not require to be educated, how to eat meat, how to drink, how to use sexual intercourse. No. It is already there. Nityā hi... Na hi tatra codanā. There is no need of encouragement. Then why the śāstra's ordering that "You eat meat in this way. You drink in this way. You have sexual intercourse in this way"? What is the purpose? The purpose is to restrict him. Because by natural propensity he'll have... Just like in Western countries there is no marriage practically. But they have sexual intercourse. They think, "Sex is there, available. Why we should bound ourselves by marriage tie?" They think like that. So why the marriage is there? Just to restrict. Without marriage, the man and woman will be open to so many other men and women. Therefore it is to restrict. One man, one woman. Otherwise, if you associate with so many men and so many women, this is animalism. So in order to check him from the animal life, sex intercourse, the marriage is there. This is the purpose. Therefore śāstra. Śāstra means simply restrict. One who is accustomed to restriction, he's perfect. Not indulgence. The animals are not restricted. But nowadays, better animal is restricted. They have got a time for sexual intercourse. But these, these animals, the four-, two-legged, two-hands animal, they have no restriction. Any time. Less than animal. Therefore śāstra is there.
