So everything, analytical study is there in the śāstras very minute, senses and power, who has got. The fish, they have got very good sensation power. Means two miles away, they get sensation there is enemy, "Somebody's coming to eat me." These are all described in the Bhāgavatam. The frogs, they can become in samādhi, situated in samādhi, for many, many years. So these things are not very great things, to have samādhi, to have yogic principle. Even in the animals you will find. I read long, long ago that in the coal mine, while they were digging coals, one frog came out from the coal and jumped over and died. That means the frog was buried within the lump of coal for many, many thousands of years, and he was keeping samādhi. Kumbhaka, kumbhaka-yoga they know. So these are not very extraordinary things. Because after all, living entity is eternal, does not die. Na hanyate hanyamāne śarīre (BG 2.20). If, by some process, he lives for some time more, that is not very wonderful thing. The wonderful thing is how to stop this birth and death. That is wonderful thing. Not that I am living, say, for fifty years or hundred years, another man is living for three hundred years. That is not very wonderful thing.
So there is regulative principles in the śāstra, as I was explaining. (aside) Why the boys shall talk? So we must follow the . . . if we want to make our life perfect, we must follow the regulative principle. Just like good citizen means . . . what is that good citizen? Good citizen means who follows the laws of the state. He is good citizen. Good citizenship means strictly following the laws of the government. Similarly, first-class human being means who follows the laws of God, that's all. He's first class. And those who are simply violating the laws of God, they are third class, fourth class, tenth class. It will be explained a few verses after that na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ (BG 7.15). Those who are simply violating the laws of God, they are called duṣkṛtinaḥ, miscreants, such class of men. There are so many classes of men. Kṛṣṇa is mentioning some of them. Na māṁ duṣkṛtino mūḍhāḥ. The duṣkṛtinaḥ, those who are simply violating the laws of God, they are called duṣkṛtinaḥ.
So such person cannot come to Kṛṣṇa consciousness, God consciousness, though one must follow the rules and regulation, śāstra. Śāstra means which is giving you regulative life. In regulative life sex life is Kṛṣṇa . . . (break) That is regulative principle. And even with your wife you cannot have sex life unless it is meant for progeny, for producing children, Kṛṣṇa conscious children, not cats and dogs. That is dharmāviruddhaḥ. That is not against religious principles. That is very nice. Just like to produce brahmacārīs. Brahmacārī . . . wherefrom the brahmacārī comes? It comes from the gṛhastha life. Unless one marries, how he can beget children who become brahmacārī? So if you produce brahmacārī, then you can produce hundreds of brahmacārī. That is allowed. But don't produce cats and dogs. That is dharmāviruddhaḥ. Kṛṣṇa says: "I am there." Everything is there. Kṛṣṇa is everything. Even in sexual intercourse there is Kṛṣṇa. But how? Dharmāviruddhaḥ, not against the laws of śāstra. In the śāstra it is said that you'll have sex life after the menstrual period, sex life you have. But when your wife becomes pregnant, no more sex life. No more sex life. This is the injunction of the śāstra.
