śrī-nārada uvāca
guruṇaivaṁ pratiprokto
bhūya āhāsuraḥ sutam
na ced guru-mukhīyaṁ te
kuto 'bhadrāsatī matiḥ
śrī-nāradaḥ uvāca - Nārada Muni said; guruṇā - by the teacher; evam - thus; pratiproktaḥ - being answered; bhūyaḥ - again; āha - said; asuraḥ - the great demon, Hiraṇyakaśipu; sutam - unto his son; na - not; cet - if; guru-mukhī - issued from the mouth of your teacher; iyam - this; te - your; kutaḥ - from where; abhadra - O inauspicious one; asatī - very bad; matiḥ - inclination.
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.
