PURPORT

Prahlada Maharaja was still a boy, and therefore his teachers thought that if they pacified the little boy he would immediately speak the truth, revealing the secret of how the Vaisnavas came there to teach him lessons in devotional service. It was surprising, of course, that in the same school the other boys of the Daityas were not polluted; only Prahlada Maharaja was supposedly polluted by the instructions of the Vaisnavas. The main duty of the teachers was to inquire who those Vaisnavas were that came to teach Prahlada and spoil his intelligence.
