So the example is set by the Supreme Personality of Godhead that human civilization will advance only on the basis of brahminical culture and cow protection. As soon as there is falldown from brahminical culture, and as soon as there is discrepancy in the protection of cows, there will be no more peace in the world. Therefore He specifically said, go-brāhmaṇa-hitāya ca. This Kṛṣṇa consciousness movement is for the protection of brahminical culture and cows. Then automatically the peace of the world will come, if two things are done. This is Vedic literature. They pick up the essence of the things, and all other things follows. Just like meditation. Meditation means... Not meditation, the yoga system. Yoga indriya-saṁyamaḥ. Yoga system means to control the senses. This is the primary factor of practicing yoga. Now the senses, we have got five senses acquiring knowledge and five working senses. So of all the senses, the tongue is considered to be the most powerful sense. The Vaiṣṇava, they therefore try to control the tongue. They do not allow the tongue to eat everything and anything. No. Svāmī or gosvāmī means who has control over the senses. Generally, people, they are servant of the senses. When people, when a man becomes, instead of becoming servant of the senses, when he becomes master of the senses, then he is called svāmī. Svāmī is not this dress. This dress is superfluous, just to... As in everywhere there is some uniform dress to understand that "He is, he..." Actually, svāmī means who has control over the senses. And that is brahminical culture. Satya śama dama titikṣa ārjavam, jñānam vijñānam āstikyaṁ brahma-karma svabhāva-jam (BG 18.42). Brahman, Brahman means brāhmaṇa, brahminical culture. Truthfulness, cleanliness, and controlling the senses, controlling the mind, and simplicity and tolerance, full of knowledge, practical application in life, faith in God—these qualifications are brahminical culture. Anywhere we practice these qualifications, he'll revive brahminical culture. It is not that in a particular country or particular society or particular class of men they are brāhmaṇas. No. Bhagavad-gītā does not say that. Brahma-karma svabhāva-jam. Svabhāva-jam, natural activities. So truthfulness, controlling the senses, controlling the mind, and simplicity, and cleanliness, and tolerance, and knowledge, and practical application of knowledge in life. So this Kṛṣṇa consciousness movement is for training brahmacārīs. Brahmacārī means who are being practiced to the brahminical culture. So, there must be a portion of the population well versed in brahminical culture. Ekaś candras tamo hanti na ca tara sahasrasaḥ. Just like in a garden if there is one nice flower plant, rose, with good scent, the whole garden becomes flavored, you see? Scented. Similarly, we do not expect that the whole population of the human society will be taking to this brahminical culture; but even one percent of the whole population accepts this brahminical culture, Kṛṣṇa consciousness, then the whole world will be peaceful. Not even one percent, less than one percent. It is so nice.
So Kṛṣṇa consciousness movement is very scientific movement. Unless you raise the population from the animal propensities, how you can expect peace? Do you think is there any peace in the dog society, in the cat society? No, it is not possible. You keep some dogs. They meet. As soon as they meet together there will be howling—"gow, gow, gow, gow." So you cannot expect if you create dog society, then you cannot expect. You have to create a portion, a certain percentage of the population, brāhmaṇas. Then there is possibility. Just like in the sky the numerical strength of the stars are greater, but there is one moon. That one moon is sufficient to illuminate the sky. Ekaś candras tamo hanti na ca tara sahasrasaḥ. Millions of millions of stars twinkling, they cannot dissipate the darkness. You see. Only one moon, only one sun. So try to make some percentage of the population actually brāhmaṇa. Go-brāhmaṇa-hitāya ca. And protect the cows. Actually, we are taking so much advantages. So from the cows, the milk. And from the milk we can make hundreds of vitaminous foodstuff, hundreds. They're all palatable. So such a nice animal, faithful, peaceful, and beneficial. After taking milk from it, if we kill, does it look very well? Even after the death, the cows supply the skin for your shoes. It is so beneficial. You see. Even after death. While living, he gives you nice milk. You cannot reject milk from the human society. As soon as there is a child born, milk immediately required. Old man, milk is life. Diseased person, milk is life. Invalid, milk is life. So therefore Kṛṣṇa is teaching by His practical demonstration how He loves this innocent animal, cow. So human society should develop brahminical culture on the basis of protecting cows. The brāhmaṇa cannot take any other food except it is made of milk preparation. That develops the finer tissues of the brain. You can understand in subtle matters, in philosophy, in spiritual science. Just like in a scientific college, not ordinary man can understand the scientific intricacies. They require some preliminary qualification to enter into the scientific college. They require some preliminary qualification to enter into the law college, in the postgraduate classes. Similarly, to understand the subtle or finer implications of spiritual science, one has to become brāhmaṇa. Without becoming brāhmaṇa it is not possible.
Therefore in the Bhagavad-gītā it is said, cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). There are four classes of men created by God: cātur-varṇyaṁ. How they are divided? How the classification is made? Guṇa-karma-vibhāgaśaḥ: by classification of quality and work. Not by birth. In India, of course, this classification of guṇa-karma-vibhāgaśaḥ was originally planned from the Vedic age. But later on, a class of men, without any qualification, without any practical work, they claimed that "I belong to such and such class." Therefore India's falldown was inevitable. So Bhagavad-gītā says, "Not like that." Bhagavad-gītā says that these classes of men, cātur-varṇyaṁ—the brahminical class, the kṣatriya class, the vaiśya class, and the śūdra class—is everywhere. Not only in India, but also throughout the whole universe, in every country, in every nation, in every society, there must be some people who have brahminical tendency. Just like from your country, we have picked up some boys and girls who are inclined to adopt this way of life. So this Kṛṣṇa consciousness movement is simply picking up where there are brahminical class of boys, girls, men. Not that we are taking account, "Oh, who is your father? Is your father a brāhmaṇa?" No. We don't take account. His father may be anything; it doesn't matter. But if he has got tendency to accept this Kṛṣṇa consciousness, we immediately welcome: "Come on." And we teach him this brahminical qualification—to become brahmacārī, not to indulge in illicit sex life, don't take nonvegetarian diet. We recommend not exactly nonvegetarian diet. We are vegetarian diet, we restrict from nonvegetarian diet, but we recommend Kṛṣṇa prasādam. We have no quarrel with the nonvegetarians, because vegetable also has got life. The plants, the grass, the trees, the fruits, the flowers, they have also life. They are not dead. So simply becoming vegetarian is no great qualification. Somebody is taking meat and somebody is taking vegetable, it does not make any difference. But we are taking vegetables not as vegetarian. We are taking as Kṛṣṇa prasādam, remnants of foodstuff offered to Kṛṣṇa.
