yāmasundara: One thing that Prabhupāda was explaining, I think, that didn't quite get cleared up was how do we discern which translation of the Gītā is most authoritative. Well, he answered when he said that Kṛṣṇa is the authority. So we have to take it in a channel from Kṛṣṇa, and there are only four lines of disciplic succession that come from Kṛṣṇa. And of these, only one is existing now, or is it two?
Yoko Ono: What do you mean by "channel"? Is it through hereditary or what?
Śyāmasundara: Lines of disciplic succession. Yes, it's hereditary. Swamiji's spiritual master...
Prabhupāda: Just like channel you'll understand very easily. You send some money order to your friend. So from which channel he'll receive? He'll receive through the post office, not through any other channel. So if the postal peon delivers it, you are confident, "Yes, the money has come." So why you give the importance to the postal peon? Because he's representative of the post office. Similarly, Kṛṣṇa is the original authority. So the Kṛṣṇa's representative is the authority. And who is Kṛṣṇa's representative? Who is a devotee of Kṛṣṇa. So therefore the devotee of Kṛṣṇa is authority, at least of Bhagavad-gītā. So you have to receive through the devotee of Kṛṣṇa about Bhagavad-gītā. One who does not know anything about Kṛṣṇa, how he can preach Bhagavad-gītā? This is common sense.
