Pradyumna: Translation: "Because of the Lord's pastimes and activities and because of His absence, it appeared that Arjuna forgot the instructions left by the Personality of Godhead. But factually this was not the case, and again he became lord of his senses." (SB 1.15.30)
Prabhupāda: Hmm. So here it is explained what is Bhagavad-gītā. Gītaṁ bhagavatā. Bhagavatā means "by the Supreme Personality of Godhead," and gīta means "spoken." They say "sung," you can say. But gīta means "spoken by." Therefore it is called Bhagavad-gītā, "the instruction given by the Supreme Personality of Godhead personally." Therefore it is called Bhagavad-gītā.
Now Arjuna said that science was spoken by the Supreme Personality of Godhead. If we read Bhagavad-gītā, then we must follow the person of Arjuna, because Arjuna directly heard Bhagavad-gītā from the Supreme Personality of Godhead. And he says that this science, gītaṁ bhagavatā. So why there should be interpretation? Because the person who heard directly from Bhagavān, the Supreme Per..., he said that this is spoken by the Supreme Personality of Godhead. So one who is hearing directly, he's saying something, but you are saying something. You have no right. This is called paramparā system. The person who heard Bhagavad-gītā directly from Kṛṣṇa, whatever he says, that is to be accepted. You cannot interpret. This is the paramparā system.
So if you want to understand Bhagavad-gītā, then we must understand in the same way as the person who directly heard from. This is called paramparā system. Suppose I have heard something from my spiritual master, so I speak to you the same thing. So this is paramparā system. You cannot imagine what my spiritual master said. Or even if you read some books, you cannot understand unless you understand it from me. This is called paramparā system. You cannot jump over to the superior guru, neglecting the next ācārya, immediate next ācārya. Just like our, this Gau..., Caitanya Mahāprabhu's cult; we cannot understand Caitanya Mahāprabhu directly. It is not possible. We have to understand through the Gosvāmīs. Therefore you'll find in the Caitanya-caritāmṛta and at the end of every chapter, the writer says,
- śrī-rūpa-ragunātha-pade yāra āśa
- caitanya-caritāmṛta kahe kṛṣṇa-dāsa
This is the process. He does not say that "I've understood Lord Caitanya Mahāprabhu directly." No. That is not understanding. That is foolishness. You cannot understand what is Caitanya Mahāprabhu. Therefore repeatedly he says, rūpa-ragunātha-pade... "I am that Kṛṣṇa dāsa, Kavirāja, who is always under the subordination of the Gosvāmīs." This is paramparā system. Similarly, Narottama dāsa Ṭhākura also says, ei chay gosāi jār mui tār dās, "I am servant of that person who has accepted this six Gosvāmīs as his master. I am not going to be servant of any other person who does not accept the way and means of..." Therefore we say or we offer our prayer to our spiritual master, rūpānuga-varāya te, rūpānuga-varāya te, because he follows Rūpa Gosvāmī, therefore we accept, spiritual master. Not that one has become more than Rūpa Gosvāmī or more than... No. Tāṅdera caraṇa-sebi-bhakta-sane vās. This is the paramparā system.
