Bhishma said Listen, O Yudhishthira! Those ordinances that I have told you of, those, viz., that were first promulgated by the great Rishis Angirasa, and that have reference to meritorious fasts for their soul, are considered as equal to Sacrifices.
भीष्म उवाच इदमङ्गिरसा प्रोक्तमुपवासफलात्मकम्॥ विधिं यज्ञफलैस्तुल्यं तन्निबोध युधिष्ठिर। यस्तु कल्यं तथा सायं भुजानो नान्तरा पिबेत्॥
