अथ यत्रैतत् पुरुषः पिपासति नाम तेज एव तत् पीतं नयते । तद् यथा गोनायो ऽश्वनायः पुरुषनाय इत्य् एवं तत् तेज आचष्ट उदन्येति । तत्रैतद् एव शुङ्गम् उत्पतितं सोम्य विजानीहि । नेदम् अमूलं भविष्यतीति
atha yatraitat puruṣaḥ pipāsati nāma teja eva tat pītaṃ nayate | tad yathā gonāyo 'śvanāyaḥ puruṣanāya ity evaṃ tat teja ācaṣṭa udanyeti | tatraitad eva śuṅgam utpatitaṃ somya vijānīhi | nedam amūlaṃ bhaviṣyatīti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
'When a man is thus said to be thirsty, fire carries away what has been drunk by him. Therefore as they speak of a cow-leader (go-nâya), of a horse-leader (asva-nâya), of a man-leader (purusha-nâya), so they call fire udanyâ, thirst, i.e. water-leader. Thus (by water digested &c), my son, know this offshoot (the body) to be brought forth: this (body) could not be without a root (cause).
