Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 2

Sanskrit:

विदुर उवाचके ते प्रचेतसो नाम कस्यापत्यानिसुव्रत ।कस्यान्ववाये प्रख्याता: कुत्र वा सत्रमासत ॥ २ ॥

ITRANS:

vidura uvācake te pracetaso nāmakasyāpatyāni suvratakasyānvavāye prakhyātāḥkutra vā satram āsata

Translation:

Vidura inquired from Maitreya: O greatly advanced devotee, who were the Pracetās? To which family did they belong? Whose sons were they, and where did they perform the great sacrifices?

Purport:

The great Nārada’s singing, in the previous chapter, of three verses in the sacrificial arena of the Pracetās gave another impetus to Vidura to ask further questions.
