750821 Conversation - Srila Prabhupada Speaks a Nectar Drop in Bombay

Nectar Drops from Srila Prabhupada
"So one yuga means forty-three lakhs of years, and multiply by it one thousand. That is Brahmā's duration of one day. Now, in one day there are seven Manus. So Vivasvān Manu's age can be calculated—at least forty millions of years ago. So the Bhagavad-gītā is not a new thing. It was spoken five thousand years ago to Arjuna. That was not the first speaking. He says, "I first spoke to the Vivasvān, the sun-god.""
