Prabhupāda: They should be trained up. Therefore Vedic civilization is training. Some section of the people, they should be very intellectuals, brain, just like to maintain this body we require first of all the brain. If the brain is not order, then other parts, they may be there, but they are also useless. So similarly, in the society, some intellectuals should be maintained. They are called brāhmaṇas, and some of the brāhmaṇas, they are sannyāsīs. They are simply meant for giving good instruction. They should personally become very good and intellectual, and they should give instruction to other people what is the value of life, how to live. This is one section. They should be free from the anxiety of maintaining themselves. The society should treat them as children and give them all necessities, bare necessities, not they are meant for living very luxuriously. No. Simple living.
Then the next class, kṣatriyas, the politicians, administrators, they are also required, to give protection to the people from injury. Kṣatriya . . . kṣat means injury, and trāyate, "one who saves people from injury." It is kṣatriya's duty. So kṣatriya should protect all the living entities, including the animals. They are also subjects. So the first, intellectual brāhmaṇas, then kṣatriya. Then vaiśyas, their business is to produce food. Food production you can do by agriculture, kṛṣi, and by giving protection to the cows. So if you get sufficient food grains, like rice, wheat, pulses, and sufficient milk—from milk you get yogurt, butter, ghee—then your all food problem is solved. You must eat. You must eat, you must live properly. So this first, second, third—the intellectual class, the administrative class and the productive class—these three classes must be there in the society. And those who cannot be grouped either of these three classes, they should generally help as worker. They are called śūdras. So the workers means . . . suppose you require a sitting place: the carpenter is there. Suppose you require a knife: so the blacksmith is there. You require clothing: the weaver is there. In this way, four classes of men: first class, second class, third class, or the intellectuals, the administrators, the producers and the general workers. This is Vedic system of division.
Brāhmaṇa . . . this is for our living condition, and then human life especially meant for spiritual realization, self-realization. For that purpose, again, another four division. Generally, the brahmacārī, student life; gṛhastha, married life; vānaprastha, retired life; and sannyāsa, renounced life. So at the end of life one should be renounced from all other responsibilities and completely devote his life for Kṛṣṇa consciousness, or God consciousness. In this way, when a person dies in God consciousness, his life is perfect. This is Vedic civilization. Eight divisions, varṇa and āśrama. And if you simply produce śūdras, working class, then you cannot have any happiness. That is not possible. And nowadays, democratic, if you send some śūdras to act as kṣatriyas, they cannot do it. You have got practical experience. In Vietnam, what happened?
Puṣṭa Kṛṣṇa: The American soldiers, they were simply taking intoxication, hunting after prostitutes and running from the enemy.
Prabhupāda: And when they were attacked, they were running away. Because they are śūdras. How they can fight? They are not trained up as kṣatriyas. Huh? Anyone who is unemployed, let him become a soldier, but he cannot fight. That is not possible. Neither this class of men can have good brain to give direction to the society. The democracy means anyone can go to the government, and because he's not kṣatriya, his only business is how to get money so long he's on the post. Just like you did not like your President, Mr. Nixon. So that is the risk. If you keep the society in chaotic condition, any department—intellectual, administration, production—they'll be all topsy turvey, and there cannot be any peace in the world.
So this Vedic scheme, varṇāśrama, is very important scheme. If possible it should be introduced and taken up very serious. That is one of the items of Kṛṣṇa consciousness movement, to reestablish the institution of varṇa and āśrama. Not by birth, but by qualification. Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). Guṇa-karma, by quality. In India, the varṇāśrama is there, but it is not organized because the government does not take care. The government is imitating Western way of life, "There is no need of brāhmaṇa, there is no need of kṣatriya, simply śūdras." Everywhere this is the position, the śūdra population. Kalau śūdra sambhavaḥ: in this age everyone is a śūdra. So it doesn't matter everyone is born śūdra, but he should be trained up. Just like in our practical life we see that everyone is not born a scientist or engineer or lawyer. Everyone is born innocent, child, then he's trained up by the guardians. Similarly, there should be a training how to become brāhmaṇa, how to become kṣatriya, how to become vaiśya. And the government should see that everyone, as he is trained up, he is working according to his quality and occupational duty. Then there will be complete peace and harmony. That human society is perfect.
