Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 29

Sanskrit:

श्रीनारद उवाचगुरुणैवं प्रतिप्रोक्तो भूय आहासुर: सुतम् ।न चेद्गुरुमुखीयं ते कुतोऽभद्रासती मति: ॥ २९ ॥

ITRANS:

śrī-nārada uvācaguruṇaivaṁ pratiproktobhūya āhāsuraḥ sutamna ced guru-mukhīyaṁ tekuto ’bhadrāsatī matiḥ

Translation:

Śrī Nārada Muni continued: When Hiraṇyakaśipu received this reply from the teacher, he again addressed his son Prahlāda. Hiraṇyakaśipu said: You rascal, most fallen of our family, if you have not received this education from your teachers, where have you gotten it?

Purport:

Śrīla Viśvanātha Cakravartī Ṭhākura explains that devotional service is actually bhadrā satī, not abhadra asatī. In other words, knowledge of devotional service can be neither inauspicious nor contrary to etiquette. To learn devotional service is the duty of everyone. Therefore the spontaneous education of Prahlāda Mahārāja is supported as auspicious and perfect.
