ओषध्यः पशवो वृक्षा वीरुदाज्यं पयो दधि। हविर्भूमिर्दिशः श्रद्धा कालश्चैतानि द्वादश॥ ऋचो यजूंषि सामानि यजमानश्च षोडश। अग्नि यो गृहपतिः स सप्तदश उच्यते॥ अङ्गान्येतानि यज्ञस्य यज्ञो मूलमिति श्रुतिः। आज्येन पयसा दधा शकृताऽऽमिक्षया त्वचा॥ वालैः शृङ्गेण पादेन सम्भवत्येव गौमखम्। एवं प्रत्येकशः सर्वं यद् यदस्य विधीयते॥ यज्ञं वहन्ति सम्भूय सहत्विग्भिः सदक्षिणैः। संहृत्यैतानि सर्वाणि यज्ञं निवर्तयन्त्युत॥
