Our real Vedic dharma is varṇāśrama-dharma. That is mentioned in every Vedic literature—in Purāṇas, in Bhāgavatam and Bhagavad-gītā, in Rāmāyaṇa, Mahābhārata. So . . . just like in the Bhagavad-gītā it is said, cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13).
Kṛṣṇa says, the Supreme Personality of Godhead that, "These four principles," cātur-varṇya, four varṇas: brāhmin, kṣatriya, vaiśya and śūdra, mayā sṛṣṭam, "it is created by Me." But people are not interested in God's creation.
But without this division of human society . . . a class of men should be brāhmin, simply interested in knowledge. Actually, that is going on. Some class of men in the human society, they are engaged in broadcasting knowledge, scientific knowledge. They are supposed to be on the brahminical qualification, because to distribute knowledge means must have good brain, must have good learning, education. Then there is question of distributing knowledge. A fool, rascal, cannot distribute.
Then next class, the politicians, administrative class, they are under the guidance of the intelligent class. They administer to keep the society in peaceful condition, in order. The next class, vaiśya, the productive class. There must be business, trade, production, agriculture; otherwise how man will live? And the śūdra class, general class, worker class, they have neither brain nor administrative power, nor can produce anything, but they can work under the direction of some higher authority. Paricaryātmakaṁ karyam śūdra-karma svabhāva-jam (BG 18.44). Śūdras.
