If we did not have the powers of perception and cognition, evidence could not be transmitted, and if we had no tendency to believe in particular modes of evidence, persuasion could not take place. All of these processes — perception, cognition, persuasion and transmission — take place through the various potencies of the Supreme Lord. The Supreme Lord Kṛṣṇa is Himself the greatest scholar and intellectual being. He manifests the transcendental scriptures within the hearts of great devotees like Brahmā and Nārada, and in addition He incarnates as Vedavyāsa, the compiler of all Vedic knowledge. In multifarious ways the Lord generates a variety of religious scriptures, which gradually bring the conditioned souls through the various phases of reentry into the kingdom of God.
