RV 6.12.3
तेजिष्ठा यस्यारतिर् वनेराट् तोदो अध्वन् न वृधसानो अद्यौत् । अद्रोघो न द्रविता चेतति त्मन्न् अमर्त्यो ऽवर्त्र ओषधीषु ॥
tejiṣṭhā yasyāratir vanerāṭ todo adhvan na vṛdhasāno adyaut | adrogho na dravitā cetati tmann amartyo 'vartra oṣadhīṣu ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Whose blaze most splendid, sovran in the forest, shines waxing on his way like the - Impeller. He knows himself, like as a guileless smelter, not to be stayed among the plants, Immortal.
Translated by Ralph T. H. Griffith (1896)
