Śrīman Hanumān-prasāda Gosvāmī, he has spoken something about Kṛṣṇa's representative. So naturally, question may be raised that how I became Kṛṣṇa's representative. Kṛṣṇa appeared five thousand years ago. I am recently born, say, seventy-six years ago. How I became Kṛṣṇa's representative, this question may be raised.
But the answer is also there, ready. We have got a disciplic succession: from Kṛṣṇa, Brahmā; from Brahmā, Nārada; from Nārada, Vyāsadeva; from Vyāsadeva, Madhvācārya; from Madhvācārya, so many disciplic succession. Later, five hundred years ago, Mādhavendra Purī, in the line of Madhvācārya. Then his disciple, Īśvara Purī; his disciple, Lord Caitanya. Lord Caitanya, we consider Him Kṛṣṇa Himself, but He also accepted a spiritual master, Īśvara Purī. So Lord Caitanya is everyone's spiritual master, but for the sake of formality, He also accepted a spiritual master so that others may learn that this is essential.
In the Vedic scriptures, Kathopaniṣad, it is said, tad-vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12). Upaniṣad, whatever is spoken in the Upaniṣad, that is gospel truth. That is the system of understanding transcendental knowledge, veda-pramāṇa, evidence from the Vedas. According to Vedic system, amongst the learned scholars, if one presents Vedic evidences, then his position is strong. Just like in law court, two lawyers are arguing. One lawyer who quotes from the law book various bona fide quotations, the judgment is given in his favor because that is authorized.
