SB Canto 3
SB 3.3.2, Purport:
No one but the Supreme Lord can become well versed in all the branches of Vedic wisdom simply by hearing once from his teacher. Nor can anyone bring a dead body back to life after the soul has already gone to the region of Yamarāja. But Lord Kṛṣṇa ventured to the planet of Yamaloka and found the dead son of His teacher and brought him back to his father as a reward for the instructions received. The Lord is constitutionally well versed in all the Vedas, and yet to teach by example that everyone must go to learn the Vedas from an authorized teacher and must satisfy the teacher by service and reward, He Himself adopted this system.
