Brāhmaṇa-kṣatriya-vaiśya. Vaiśya means the productive class of men. Their business is how to produce food for all the society and give protection to the cows. Kṛṣi-gorakṣya-vāṇijyaṁ vaiśya-karma svabhāva-jam (Bg 18.44). There must be sufficient milk in the human society. If you drink more milk and milk products, then your brain will be very sharp. You will understand things very nicely, corectly. Therefore milk is very important. In the Vedic śāstra cow protection is recommended. Why? Because milk is very, very important thing. Milk is... What about the meat-eaters? If there are meat-eaters, they can eat other animals, but especially they should not eat the cow. They should give them protection. So because the vaiśyas, the first class, second class, third class, they are meant for producing food for the society... So milk is very important. Therefore it is recommended, kṛṣi-gorakṣya-vāṇijyam. And if there is excess, they can trade. And this is the first class, second class, third class. And those who cannot act as first-class men or as second-class men or third-class men—that means fourth-class men—they are called laborer or worker class of men.
So it is not that because one person is belonging to the worker class and another person is becoming the first class, there is differentiation. No. Everyone is important. Just like in this body the head is very important. That is a fact. If the head is cut off, then whole body is finished. But that does not mean that head is simply required without leg. Leg is also required; the hand is also required; the belly is also required. Similarly, the first-class man, the second-class man, the third-class man and the fourth-class man, all of them are equal provided they are adjusted for the higher aim of life, the higher aim of life—the brain. The brain means... First-class brain means to realize self, to understand God, and do accordingly. This is required. This is called varṇāśrama-dharma. So unless one takes to the varṇāśrama-dharma as they are prescribed, it is not human society. It is cats' and dogs' society, and you cannot be happy, however you may adjust, in a society who is filled up with cats and dogs. That is not possible.
So this Vedic instruction, it is not meant for any particular person, any community or any country. It is meant for everyone. So we should take advantage. We are therefore publishing in English so many books so that people may understand. English language is spoken practically all over the world, and we are selling also. These books are being appreciated by the professors in university and highly learned circles, and common men also. So I am lecturing for, say, half an hour or forty-five minutes—it is not possible to explain all the Vedic intelligence—but we are distributing these books. I request you to read all these books as far as possible and take advantage of do not spoil your life simply for meeting the necessities of this body very hardly like cats and dogs. It is not required. The real business is to realize your self." That is Tapo divyam (SB 5.5.1). For which And actually we do not require very much to work for meeting the necessities of life, because from the śāstras we can understand that our necessities of life are already there. They are. Tasyaiva hetoḥ prayateta kovido (SB 1.5.18). The śāstra says that "Don't bother yourself about the necessities of life. This is already there, settled. You will get it. Depend on the supplier of the necessities of life. The supplier of necessities, life, is God." That is the description in the Vedic literature. Therefore we see practically that Christians, they go to church and they request God, "O God, father, give us our daily bread." Actually it is supplied by Him. So there are 8,400,000 different forms of life, and God is the creator of them, and He is supplying all the necessities of them. We human being, we have got different enterprises, but what the enterprises have got the elephant in Africa? There are millions of elephants. Who is feeding them? And the ant also. There are trillions and millions of ant in your room. Who is feeding them? So we do not believe in God. That is our defect. Otherwise, if God is providing food for the lower animals, why not for us if we become God conscious?
So there is no reason. We shall get. But we have been habituated for economic development. Let us do it. It doesn't matter. But don't forget God. That is wanted. If you forget God, then you are no better than dog. This is the movement of Kṛṣṇa consciousness movement, that we are reminding everyone that "Don't remain like lower animals. You have got this opportunity of human life. You go, accept little austerity." So what we are prescribing, austerity? Just like these European, American boys. They are under training. Our first business is to take declaration that the devotee will not indulge in illicit sex life, not meat-eating, no intoxication and no gambling. This is austerity. And chant Hare Kṛṣṇa. It is very easy. It is not very difficult. Just like these boys, girls, they are chanting Hare Kṛṣṇa, and they are undergoing the austerity. So they have not died. Not they are unhealthy. You can see. They are living, and they will live. But they have become purified. Tapo divyaṁ yena sattvaṁ śuddhyet (SB 5.5.1). This is purifying our existence. Purifying existence means no more material body. Tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). These are the information we get, that if we purify our existence, our existential position, then the result will be that... Tyaktvā deham. We have to give up this body. The cats and dogs also will give up, and I'll also give up. That's a fact. But the cats and dogs, they'll get another material body, but if you purify your existential position, then tyaktvā dehaṁ punar janma naiti (BG 4.9), you'll not to have, accept any more material body. You shall stay in your spiritual body. And when you stay in your spiritual body you become equal with God—sac-cid-ānanda: eternal, ānanda, blissful, and full of knowledge. That is the human form of life..., er, aim of human mission. Don't miss this. There is ample information. The practice is very easy. Anyone can do it.
So our only request is take advantage of this Kṛṣṇa consciousness movement. Try to understand it properly. It is not meant for any particular person, nation, or community. It is for every human being. So we request you to study this movement and take to it seriously. Then you will be all happy.
