The next class is called the kṣatriya. Just like when somebody comes to attack you, first of all your brain gives you dictation, "Now this man is coming to attack you. You spread your hand." So immediately my hand spreads and I want to protect myself. So these are called kṣatriya class, or the armies, from "arm." So next-intelligent class is the government class, administrator class. Then next-intelligent class is third class. First class, brāhmaṇas, second class, the kṣatriyas, and the third class, the vaiśyas, who maintain the society for economic condition, development of economic condition, because we require things to consume to maintain this body. So these are called mercantile class, and the ordinary man who is neither brāhmaṇa nor kṣatriya nor vaiśya, he is called śūdra.
So this is natural, natural division of the society. Unless human being comes to the natural division . . . there is, but sometimes it happens that a śūdra is taking the place of the brāhmaṇa or the brāhmaṇa is obliged to act as a śūdra. Then there is anomaly. There is some chaos in the society. So at the present moment the education department does not distinguish who is a brāhmaṇa, who is a kṣatriya, who is a vaiśya or a śūdra. And because the things have topsy-turvied, there is chaos all over the world, not only here or there, because the division of labor or the division of working has been overlapped.
Now this Kṛṣṇa consciousness movement is meant for creating some brāhmaṇas, or the most intelligent class of men. There is no hindrance. Anyone can become brāhmaṇa. Just like in education anyone can become engineer, anyone can become medical practitioner or anyone can become lawyer if he takes such education from the very beginning, similarly, brāhmaṇa, kṣatriya, vaiśya, śūdra, there are natural division of the society. But at the present moment there is scarcity of brāhmaṇa. Brāhmaṇa means who has got very nice intellectual brain, who can understand the Absolute Truth. He is called brāhmaṇa. So this Kṛṣṇa consciousness movement is trying to create some good brains so that he can understand, one can understand what is the Absolute Truth. This is the movement.
