Prabhupāda: So we have got evidences that his varṇāśrama system is current at least for the five thousand years, varṇāśrama system. And this varṇāśrama system is mentioned in the Viṣṇu Purāṇa also. Varnāśramācaravata puruṣeṇa paraḥ pumān
(CC Madhya 8.58). Varnāśrama acaravata. So that is stated in the Viṣṇu Purāṇa. And so varṇāśrama-dharma is not a, within any historical period calculated in the modern age. It is natural. And in the Śrīmad-Bhāgavatam the comparison is given, just like in your body, in my body, there are four divisions, the face, facial, or the brain division, and the arms division, the belly division, and the leg division, similarly, by nature's way these four divisions are existing in the social body. You may take history wherever you begin, but this is existing. A class of men, they are considered to be brain. A class of men, they are considered to be the arms, administrators. And a class of men, they are called productive class. So there is no need of tracing the history. It is naturally existing from the day of creation.
