Once on a time, having finished his morning rites, the intelligent Shuka approached with a controlled mind his father, that foremost of Rishis, viz., the Island-born Krishna, who knows the distinction between the superior and the inferior, and saluting him, said, What is that sacrifice which appears to you as the foremost of all sacrifices?
ऋषीणामुत्तमं धीमान् कृष्णद्वैपायनं शुकः। अभिवाद्याह्निककृतः शुचिः प्रयतमानसः॥ पितरं परिपप्रच्छ दृष्टलोकपरावरम्। को यज्ञः सर्वयज्ञानां वरिष्ठोऽभ्युपलक्ष्यते॥
