RV 6.66.10
त्विषीमन्तो अध्वरस्येव दिद्युत् तृषुच्यवसो जुह्वो नाग्नेः । अर्चत्रयो धुनयो न वीरा भ्राजज्जन्मानो मरुतो अधृष्टाः ॥
tviṣīmanto adhvarasyeva didyut tṛṣucyavaso juhvo nāgneḥ | arcatrayo dhunayo na vīrā bhrājajjanmāno maruto adhṛṣṭāḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Bright like the flashing flames of sacrifices, like tongues of fire impetuous in their onset, Chanting their psalm, singing aloud, like heroes, splendid from birth, invincible, the Maruts.
Translated by Ralph T. H. Griffith (1896)
