Prabhupada's lecture - Śrīmad-Bhāgavatam 1.5.35 - Vṛndāvana, August 16, 1974
So our Kṛṣṇa consciousness movement does not say you stop anything. No. Whatever you have got liking, you can do, but bhagavat-paritoṣaṇam. By your work you try to satisfy Kṛṣṇa. This is our proposal. We do not say the negative, stop. No. And it is confirmed in the śāstras, ataḥ pumbhir dvija-śreṣṭhāḥ... Generally, according to Vedic principle, there are four division of karma. Not four; eight division. According to varṇa and āśrama. Ataḥ pumbhir dvija-śreṣṭhā varṇāśrama-vibhāgaśaḥ. The division of work must be there; otherwise the society cannot go on very nicely. If everyone is brāhmaṇa, not interested in anything material or simply... Because it is, after all, material world, if everyone becomes brāhmaṇa, now 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 you are constructing this temple. If we devotees remain Hare Kṛṣṇa, then who will construct this temple? Everything is required. We do not say that "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. So 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 it. Don't care for the body." No. Why?
