| "Now, this Bhagavad-gītā was spoken five thousand years ago, and Bhagavad-gītā it is said that 'This system of Bhagavad-gītā was first spoken by Me to the sun-god'. So if you take estimation of that period, it comes forty millions of years. So whether the European scholar can trace out the history of at least for five thousand years together, not to speak of forty millions? So we have got evidences that this varṇāśrama system is current at least for the five thousand years, varṇāśrama. 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."
