It is the arrangement of God that cow's milk . . . cow's own milk, she does not drink. She eats grass. That means God's arrangement is like that, that "Let the human being drink the milk of cow, and the cow may eat grass." Because they haven't got good brain. Foodstuffs should be given, nice foodstuff given, should be given to the particular person for developing nice brain. Milk is a foodstuff which can develop your finer tissues of the brain so that you can understand higher philosophy. And if you become blunt, and you eat meat by killing any animal, then how you will understand? The finer tissues given in the human form of life for understanding spiritual things . . . you cannot.
Vinā paśughnāt. Therefore Parīkṣit Mahārāja says, vinā paśughnāt. Nivṛtta-tarṣair upagīyamānād bhavauṣadhāc chrotra-mano-'bhirāmāt, uttamaśloka-guṇānuvādāt (SB 10.1.4). Uttamaśloka, Kṛṣṇa, guṇānuvādāt, glorifying His activities, who can be bereft of this opportunity, vinā paśughnāt, unless he is a animal-killer? Unless he is animal-killer, nobody will deny to hear about Kṛṣṇa. Because the animal-killers, they have lost their brain. But Caitanya Mahāprabhu's mercy is so great that even who has lost his brain, he can be revived by hearing Hare Kṛṣṇa mantra. That is Caitanya Mahāprabhu's . . . ceto-darpaṇa-mārjanam (CC Antya 20.12). Yes, in this age everyone is fallen. But he can be, I mean to say, elevated to the position of nice brain. How? By paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam. Simply by chanting.
So in this age everyone is blunt-headed, animal-killer. They cannot understand what is kṛṣṇa-kathā, what is spiritual life. We see actually: they are not at all interested. They feel disturbance: "What these people are chanting Hare Kṛṣṇa?" They cannot make any solution of the problems. Just like Atreya Ṛṣi was speaking that government is embarrassed how to solve the question of intoxication, LSD-taking. They could not. Huge amount they are spending. But here is the remedy, they will not take. Why? Paśughnāt, killing, animal-killers. So animal-killer cannot take it. Vinā paśughnāt (SB 10.1.4). Vinā means without. Unless one is animal-killer, he cannot give up this opportunity of hearing about Kṛṣṇa. Therefore we forbid, "No meat-eating." This is the qualification. Unless you stop meat-eating, you cannot understand. Blunt head.
So the hog has been especially mentioned because he has no discrimination of food. Our Ramakrishna Mission, they say, "What is there in food? Whatever you like, you can eat. It has nothing to do with spiritual life." Nonsense. You see? Āhāra, śuddha āhāra. Even George Bernard Shaw, he wrote one book that "You are what you eat." Actually, that is so. Why there are so many varieties of foodstuff? Because there are varieties of men. Those who are meat-eaters, if you give them so many varieties of fruits and sandeśa and rasagullā, he won't like it. He won't like it. If before the hog you put nice, first-class halavā, "No, sir. Stool. Give me stool." Therefore hog. All right.
One who has no discrimination of foodstuff, he is going to be hog next life. That is the punishment by nature. One who are loitering in the street naked, they are going to have next life tree, "Stand up naked for ten thousand of years. That's all right." But they are enjoying. They're showing beauty by naked, nakedness. But nature will not tolerate. Prakṛteḥ . . . daivī hy eṣā guṇamayī mama māyā . . . (BG 7.14). There is nature. They do not consider how one living entity has got the body of a tree, how one living entity has got the body of a hog, how one living entity has got the body of a demigod, how one has got the body of a Vaiṣṇava. They do not know. They do not know. The education is so cramped, they do not even consider that these are . . . they say, Darwin's theory, "Developing the body."
So the education is going on in that way. This is our position. You should take advantage of the scientific knowledge given by Śrīmad-Bhāgavatam. Śrīmad-bhāgavatam amalaṁ purāṇam (SB 12.13.18). Amalaṁ purāṇam, spotless education, Śrīmad-Bhāgavatam. Therefore, in the beginning of Śrīmad-Bhāgavatam it is said, dharmaḥ projjhita-kaitavo 'tra (SB 1.1.2). Atra śrīmad-bhāgavata. "In this Śrīmad-Bhāgavatam, cheating type of religious system is kicked out." Kicked out. In religion where there is no discrimination of foodstuff, what is that religion? What is that religion? This is fanaticism. That is not religion. Religion is to understand God. And one cannot understand God, the purest of all pure, unless one is pure.
