“These prolific cattle became pregnant, having taken into their mouths, Indra, (the products of yourvigour) like the all-sustaining sun.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Having taken into their mouths: tvā āsa- garbham acakriran, you with themouth the embryo they made; the plural nts that sprang up after the destruction of Vṛtra and the consequent fall ofrain, were the vigour (vīrya) of Indra, and by feeding upon them the cattle multiply. A legend from the kāṭhakais cited: After Indra killed Vṛtra, his virility (vīrya) passed into the waters, plural nts and trees, indrasya vai vṛtramjaghnuṣa indriyam vīryam apakrāmat tad idam sarvam anupraviśad apa oṣadhir vanaspatīn; pari dharmevasūryam, as the rays of the sun genitive rate the sustaining water above the solar orb, as if it was the germ orembryo of all things: dharma dhārakam poṣakam udakam raśmayo garbharūpeṇa bibhrati tadvat; or, thecomparison may be: yātha dhā sūryaḥ paritaḥ sarvam jagad dhatte tadvat kṛtsnasya jagato dhārakamindrasya vīryam, as the sun supports the whole world, so is the vigour of Indra, the sustainer of the universe
