In the Bhagavad-gītā you'll find Kṛṣṇa says that the four divisions of society: brāhmaṇas, kṣatriya, vaiśya and śūdra... That is natural. Somebody is inclined for spiritual advancement, oh, they should be picked up as brāhmaṇas. Now, we are training boys who are spiritually inclined, and now unnecessarily we are being called for military service. Just see, how discrepancy! The foolish person has no knowledge that "This boy is being trained up in higher science. Why he should be disturbed?" But they have no idea. Therefore imperfect. The intellectual persons, those who have got brahminical qualification... These boys are being restrained for being trained up as brāhmaṇa, brahmacārī. They don't take, I mean to say, meat-eating; they don't take part in intoxication; they don't take part in gambling; they don't take part in illicit sex life. So they are being trained as complete brāhmaṇa, the highest intellectual person, purified person in the society. If there is one brāhmaṇa in a family, or one society, the whole family, whole society becomes sanctified.
So these rascals, they have no knowledge how to train as brāhmaṇa, how to train as kṣatriya, how to train as vaiśya. Just like, of course, in other field of action, in the śūdras and vaiśyas, there is nice training in your country. If anyone wants to become a businessman, oh, there is training, colleges and schools, technological. That's nice, very nice. But why everyone should be dragged for technology? This is foolishness. Just like in your body, for maintenance, proper maintenance of the body you require the head, you require the arms, you require the belly, you require the legs. So all these four divisions of the body required. You cannot say, "Oh, we don't require this head." Oh, it is nonsense. You require everything. You require the head, you require the arms, you require the belly, and you require the leg. This is fit body. Suppose if there is a body without head—oḥ, it is dead body. It is body undoubtedly, but if there is no head, simply the trunk is there, it is called dead body. The head is considered to be the intellectual part of the body. Similarly, if there is no brāhmaṇa in the society, that is a dead body. If there is no spiritual man in the society, that is a dead society.
This is very nice, natural division. Therefore Bhagavān Kṛṣṇa says, cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ: (BG 4.13) "I have created the four divisions of society according to quality and work." If somebody is working just like a brahmacārī, brāhmaṇa, and he has acquired the quality... What is that quality? To understand Kṛṣṇa or the Supreme Lord. So he's a brāhmaṇa. Why he should be called for the action of the arms? The arms for defending, that is kṣatriya. Of course, that is required. To protect the country, to protect the society, military arrangement should be there. Nobody disapproves. But not the brāhmaṇas. It is putting the horse before a cart. Horse is required for different purpose. Another beast of those, asses, mules and bulls, they are required for towing cart.
So there is derangement of the social order in the present-day world. Why? There is no head. They are all rascals. I frankly say it. Anybody may come. Any society where there is no intellectual persons or Kṛṣṇa consciousness, that is a rascal society because there is no head. Either it is madman or a headless man, or dead body. If there is no brain, there is no head. If the brain is not working properly, then he's a madman. And if there is no head at all, then he's a dead man. So do you think in a dead society or in a mad society there can be any peace? No. What is peace? If the dead..., society is already dead, what do you mean by peace? And if the society is all full of madmen, then where is the question of peace?
Therefore Kṛṣṇa consciousness is the most important subject of the present-day society. The responsible men who are leading the society, the president, or the secretaries, or the mayor, they should have intelligence to understand. But if we approach... The other day when I was coming to your country, I met in Japan, Tokyo, one chief secretary of the governor. I wanted to explain to him that "You just cooperate with this movement." He said, "Oh, we are secular. We cannot cooperate with any religious movement." Just see. He's one of the chief secretaries of the governor, and he's such a fool. He is taking this movement as religious movement. Just like they have got so many sentimental religions. Oh, it is not sentimental. It is the necessity of the society that a class of men should be Kṛṣṇa conscious. Otherwise the society is doomed. It is going to hell. They have no brain.
So brainless persons, rascals are on the head of government. How there can be peace? How you can expect peace in the dog's society? The dogs are by nature howling—"How, how, how"—as soon as he sees another dog. So do you mean to say there can be peace? So if you turn human society into dog society, into cat society, into tiger society... Tiger is very powerful. He can kill many other animals. Does it mean it is very important animal? No. It has no use in the society. Undoubtedly, it is very powerful. It has got the good weapons to fight and it can kill many. These are not qualifications for good men or good society. Why you are afraid of a tiger? Why you are afraid of a monkey? So we are not meant to manufacture a society of monkeys or tigers or asses and mules. The asses, they work very hard. Do you mean to say a society of ass will derive any benefit? No. We want human society. Human society. Otherwise, what is the use of becoming human being?
So the situation is so difficult that... It is very difficult to push on this movement, but still we have to do it. And this is the highest yoga. If you push on this movement of Kṛṣṇa consciousness, then you'll be performing the highest type of yoga. Don't be misled by so-called yogas. This is yoga. Yoga means cooperation, cooperation with the Supreme. Just like the head. Head, if the head... The head means head, chief. Why this part of the body is called head? Because it is chief. The brain is working. It orders the hand, "Come here." It comes. Oh. Therefore it is head. It at once orders the leg, "Go on," "Oh, I must walk." Therefore it is head. So a section of person must be head of the society. They must order, and others will work. Then there will be peace. Then there will be peace. But if the leg takes the part of working like head, how it can work? Leg is accustomed to carry order to walk. It cannot work as the brain. Therefore, when the śūdras or the leg take the part of the head, working like head, it is all disorder. It is all disorder. Therefore this yoga system, Kṛṣṇa consciousness yoga system, should be popularized. It is essential in order to stop all nonsense propaganda.
