Guest (3): Lord Kṛṣṇa preached Bhagavad-gītā in battlefield of Kurukṣetra, and it is afterwards written by Vyāsadeva.
Prabhupāda: Yes.
Guest (2): Is the Vyāsadeva got it out of his meditation, or how the actual thing which was conveyed to Arjuna was again in real thing took a shape in Bhagavad-gītā?
Prabhupāda: That you have no intelligence to understand. But what is given by Vyāsadeva, that is accepted by all the ācāryas. We are not so learned as you are, but we follow the ācārya. And it is recommended in the Bhagavad-gītā, ācāryopāsanam. You must follow the ācāryas, the Rāmānujācārya, Madhvācārya, even Śaṅkarācārya, Caitanya Mahāprabhu. Then you'll get the real answer. Ācāryavān puruṣo veda: "One who follows the ācārya, he knows." Others, they do not know. So you cannot question "Why? How Vyāsadeva wrote?" That is stated in the Bhagavad-gītā. Sañjaya says vyāsa prasāda. How one can understand? By the mercy of Vyāsadeva. So we have to see. Instead of criticizing in that adverse way, we have to follow the ācārya. Ācāryopāsanam. So you'll find Rāmānujācārya, Madhvācārya, Viṣṇu Svāmī, Nimbārka, Śrī Caitanya Mahāprabhu, they have accepted in that way. So what is the use of our questioning? We should follow. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). Otherwise it is not possible.
