RV 7.101.1
तिस्रो वाचः प्र वद ज्योतिरग्रा या एतद् दुह्रे मधुदोघम् ऊधः । स वत्सं कृण्वन् गर्भम् ओषधीनां सद्यो जातो वृषभो रोरवीति ॥
tisro vācaḥ pra vada jyotiragrā yā etad duhre madhudogham ūdhaḥ | sa vatsaṃ kṛṇvan garbham oṣadhīnāṃ sadyo jāto vṛṣabho roravīti ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Speak forth three words, the words which light precedeth, which milk this udder that produceth nectar. Quickly made manifest, the Bull hath bellowed, engendering the germ of plants, the Infant.
Translated by Ralph T. H. Griffith (1896)
