ITRANS:
śrī-daitya-putrā ūcuḥprahrāda tvaṁ vayaṁ cāpinarte ’nyaṁ vidmahe gurumetābhyāṁ guru-putrābhyāṁbālānām api hīśvarau
Translation:
The sons of the demons replied: Dear Prahlāda, neither you nor we know any teacher or spiritual master other than Ṣaṇḍa and Amarka, the sons of Śukrācārya. After all, we are children and they our controllers. For you especially, who always remain within the palace, it is very difficult to associate with a great personality. Dear friend, most gentle one, would you kindly explain how it was possible for you to hear Nārada? Kindly dispel our doubts in this regard.
