What forms the character of sacrifice as sacrifice? What is that upon which sacrifice rests? What is that which is considered as the best by the deities? What is that sacrifice which is above the sacrifices of this world? Do you also tell me, O father what is that which is the most sacred of all things.
किं च यज्ञस्य यज्ञत्वं क्व च यज्ञः प्रतिष्ठितः। देवानामुत्तमं किं च किं च सत्रमितः परम्॥ पवित्राणां पवित्रं च यत् तद् ब्रूहि पितर्मम।
