RV 10.65.6
या गौर् वर्तनिम् पर्येति निष्कृतम् पयो दुहाना व्रतनीर् अवारतः । सा प्रब्रुवाणा वरुणाय दाशुषे देवेभ्यो दाशद् धविषा विवस्वते ॥
yā gaur vartanim paryeti niṣkṛtam payo duhānā vratanīr avārataḥ | sā prabruvāṇā varuṇāya dāśuṣe devebhyo dāśad dhaviṣā vivasvate ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The cow who yielding milk goes her appointed way hither to us as leader of holy rites, Speaking aloud to Varuna and the worshipper, shall with oblation serve Vivasvan and the Gods.
Translated by Ralph T. H. Griffith (1896)
