RV 10.69.2
घृतम् अग्नेर् वध्र्यश्वस्य वर्धनं घृतम् अन्नं घृतम् व् अस्य मेदनम् । घृतेनाहुत उर्विया वि पप्रथे सूर्य इव रोचते सर्पिरासुतिः ॥
ghṛtam agner vadhryaśvasya vardhanaṃ ghṛtam annaṃ ghṛtam v asya medanam | ghṛtenāhuta urviyā vi paprathe sūrya iva rocate sarpirāsutiḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Butter is that which makes Vadhryaiva's fire growstrong: the butter is its food, the butter makes it fat. It spreads abroad when butter hath been offered it, and balmed with streams of butter shines forth like the Sun.
Translated by Ralph T. H. Griffith (1896)
