Bhagavat-toṣaṇam, we must know first of all who is God, who is Bhagavān. So śāstra says, authority says, and history says. What more proof you want? Huh? What more proof? Is there anyone to challenge Kṛṣṇa? Everything is there. Still, why you are searching after God? This is foolishness. This is foolishness. Owls', owls' philosophy. Owls' philosophy . . . the owl will not open the eyes to see the sun. Just open your eyes, you see, this here is sun. "No, there is no sun." This is owls' philosophy. Close the eyes; meditate. And the God is here, "No, I'll not open my eyes."
So we do not follow this philosophy, owls' philosophy. We follow real philosophy. What is that real philosophy? Śruti-pramāṇam, evidence from the Vedas, history, aitihya-pramāṇa, history. And anumāna-pramāṇa. There are many: pratyakṣa, anumāna, aitihya . . . so out of that, there are so many evidential processes, but according to followers of the Vedic principle, their process is śruti-pramāṇam. Śruti-pramāṇam means if it is mentioned in the Vedas, Upaniṣad, then it is pramāṇam. Śruti-pramāṇam. So Vedas, there are four Vedas and 108 Upaniṣads, and then eighteen Purāṇas, then this Mahābhārata. So all these are Vedic literatures. Śrīmad Madhvācārya describes them, these are Vedic literature. Not only the four Vedas—Sāma, Yajur, Ṛg, Atharva—but expansion of Vedas. Purāṇas, they are also Vedas.
