You must keep the whole things—the head, the arms and the belly and the legs. Then your body is a healthy condition and will work very nicely. When you have to do something, you have to tax your brain. That is the business of the brain. When you have to protect yourself, your hands will be required. If somebody comes to attack you, you immediately expand your hand or take some weapon to protect yourself. So this is necessary. And when you want to digest food, the belly is required. Because without digesting food, where shall you get the strength? That is also required. And when you want to move, the legs are required.
Similarly, the society should be divided into four classes of men. The persons who are really possessing brain, that is Kṛṣṇa consciousness men. So at the present moment there is need of such men. What kind of men? Kṛṣṇa conscious. What is that Kṛṣṇa conscious man? One who knows himself and knows God. That is first-class intelligent man. The society is now practically is composed of the legs and the belly. The hands and heads are gone of the human society. So there is confusion, because there is no head who can give you good consultation how life should be led, how we should make progress in life, how we shall fulfill our human mission of life.
