Srutayo vibhinnaḥ. Literatures are also, authentic literatures . . . śrutayaḥ means authentic literature, which is acceptable. They are also various type. Just like Vedas. There are four Vedas: Sāma Veda, Yajur Veda, Atharva Veda, Ṛg Veda. Then the Upaniṣads are there, then the Vedānta-sūtra is there. So if we study all this Vedic literature or any other similar literature, it is very difficult to find out the Absolute Truth. Śrutayo vibhinnaḥ. And if we take the philosophers, so one philosopher differs from another philosopher. Na cāsāv ṛṣir yasya mataṁ na bhinnam.
Therefore, to approach the Absolute Truth, God, is very difficult subject matter. Therefore our principle is mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). Mahājana means the recognized persons—recognized by the Supreme Lord—such persons we follow. We have got a list of recognized persons, just like Lord Brahmā, Lord Śiva, the Manu. Just like in the Bhagavad-gītā, Manu's name is there. Imaṁ vivasvate yogaṁ proktavān aham avyayam, vivasvān manave prāha (BG 4.1), this Manu.
