RV 3.30.14
महि ज्योतिर् निहितं वक्षणास्व् आमा पक्वं चरति बिभ्रती गौः । विश्वं स्वाद्म सम्भृतम् उस्रियायां यत् सीम् इन्द्रो अदधाद् भोजनाय ॥
mahi jyotir nihitaṃ vakṣaṇāsv āmā pakvaṃ carati bibhratī gauḥ | viśvaṃ svādma sambhṛtam usriyāyāṃ yat sīm indro adadhād bhojanāya ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
A mighty splendour rests upon her bosom: bearing ripe milk the Cow, unripe, advances. All sweetness is collected in the Heifer, sweetness which Indra made for our enjoyment.
Translated by Ralph T. H. Griffith (1896)
