The Vaiṣṇava philosophy begins from surrender. Therefore Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). That is the order of Kṛṣṇa. And what is the difference between Kṛṣṇa and His representative? The representative says that, "You surrender to Kṛṣṇa." He never says that, "You surrender to me. I have become Kṛṣṇa." That is a nonsense, rascal. He will say the same thing. Therefore he's Kṛṣṇa's representative. Kṛṣṇa is personally asking that, "You surrender to Me," and it is the duty of this bona fide spiritual master, guru, to say to his disciple that, "You surrender to Kṛṣṇa." He'll never say that, "You surrender to Me. I have become Kṛṣṇa. Now I am realized soul, I have become Bhagavān." He's a rascal.
So these are the process. Tad viddhi praṇipātena paripraśnena sevayā (BG 4.34). Here it is also, the same thing. The same thing is said in a different way. That is śāstra. Actually, as Kṛṣṇa says in the Bhagavad-gītā . . . what is Veda? There are four Vedas and 108 Upaniṣads, then Vedānta-sūtra, then so, so many books. All of them are Vedas. And what is the purpose? Vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). You read all the Vedas, all the Purāṇas, Brahma-sūtra, Rāmāyaṇa, Mahābhārata. What is the purpose? To understand Kṛṣṇa. If you don't understand Kṛṣṇa, then it is useless. Your so-called study of Vedas are useless. Śrama eva hi kevalam. That is the confirmation of Śrīmad-Bhāgavatam.
