If everyone becomes brāhmaṇa, no it will not go. There must be others. Kṣatriyas means the statesman, protector, politician, diplomat. Kṣatriyas. And there must be vaiśyas also, productive class of men. They must produce. Economic development, that is also required. Otherwise, how human society will go on? Not only intelligent class of men—the protector class of men, the productive class of men and the worker class of men. Suppose we are constructing this temple. If we devotees remain "Hare Kṛṣṇa," then who will construct this temple? Everything is required. We do not say this, "Stop this" or "Stop that." No.
So that division, different division, is scientifically made in the Vedic conception of life, varṇāśrama: four varṇas and four āśramas. Āśrama for spiritual advancement and varṇas for material advancement. So we want both of them, because our life is combination of spirit and matter. It is not that . . . to make the best use of a bad bargain. Suppose you have got a car. It is not very good car. It's not American car, but Ambassador. (laughter) Thrice breaks. But you have to utilize it. Bad bargain. Similarly, some way or other, we have got this material body; we cannot neglect it. We don't say that, "Neglect. Don't care for the body." No. Why?
That is the instruction of the Gosvāmīs: anāsaktasya viṣayān yathārham upayuñjataḥ (Bhakti-rasāmṛta-sindhu 1.2.255). Don't be attached to the bodily demands. Bodily demands means eating, sleeping, sex life and defending. These are bodily demands. So if we say that "I am not this body, so I don't care for this eating, sleeping . . ." no. That is not. It is not vairāgya. This kind of renunciation is not recommended by our Kṛṣṇa consciousness movement. Kṛṣṇa consciousness movement, the Gosvāmīs recommend anāsaktasya viṣayān. You do not be attached to the demands of the body, but you utilize it for advancing in Kṛṣṇa consciousness. Eating is required. If you don't eat nicely, then body cannot be maintained. But anāsaktasya viṣayān yathārham (Bhakti-rasāmṛta-sindhu 1.2.255). Eating is required, but not eating too much—not eating to the taste of the tongue, unnecessarily eating meat, fish, eggs. Why? You are human being. For you, Kṛṣṇa has given so much varieties of foodstuff: fruits, vegetables, nice rice, ḍāl, milk, ghee. Why should you go to the meat-eating? This is required. You eat like human being, not like cats and dogs. But eating is not prohibited. That is not our philosophy. Don't eat like cats and dogs, but eat like human being.
Similarly, sleeping also. Sleep; you require some rest. But don't sleep twenty-six hours. Not like that. Utmost six hours to eight hours, sufficient for any healthy man. Even the doctor says, if anyone sleeps more than eight hours, he is diseased. He must be weak. Healthy man sleeps at a stretch six hours. That is sufficient. That's all. And those who are tapasvīs, they should reduce sleeping also. Just like the Gosvāmīs did: only one and a half hour or utmost two hours. That also sometimes not. Actually, we should reduce this. Nidrāhāra-vihārakādi-vijitau. This is gosvāmī. Gosvāmī does not mean go-dāsa. Go means senses, and dāsa means servant. If we keep the title gosvāmī and become servant of the senses, it is cheating. You must be gosvāmī, means you must be master of the senses. Self-control. So what the Gosvāmīs did? Nidrāhāra-vihārakādi-vijitau cātyanta-dīnau ca yau. Very humble and . . . Nidrā means sleeping, āhāra means eating and vihāra means sense enjoyment. Vijitau, they conquered over.
