Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 7
Sanskrit:
तत्र तावत् क्रियायोगो भवतां किं विचारित: । अथवा लौकिकस्तन्मे पृच्छत: साधु भण्यताम् ॥ ७ ॥
ITRANS:
tatra tāvat kriyā-yogobhavatāṁ kiṁ vicāritaḥatha vā laukikas tan mepṛcchataḥ sādhu bhaṇyatām
Translation:
Such being the case, this ritualistic endeavor of yours should be clearly explained to Me. Is it a ceremony based on scriptural injunction, or simply a custom of ordinary society?
