SB 7.5.10
buddhi-bhedah para-krta
utaho te svato ’bhavat
bhanyatam srotu-kamanam
gurunam kula-nandana
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O best of your family, has this pollution of your intelligence been brought about by you or by the enemies? We are all your teachers and are very eager to hear about this. Please tell us the truth.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Prahlada Maharaja’s teachers were astonished that a small boy could speak such exalted Vaisnava philosophy. Therefore they inquired about the Vaisnavas who stealthily taught it to him, in order that these Vaisnavas might be arrested and killed in the presence of Prahlada’s father, Hiranyakasipu.
