RV 6.21.3
स इत् तमो ऽवयुनं ततन्वत् सूर्येण वयुनवच् चकार । कदा ते मर्ता अमृतस्य धामेयक्षन्तो न मिनन्ति स्वधावः ॥
sa it tamo 'vayunaṃ tatanvat sūryeṇa vayunavac cakāra | kadā te martā amṛtasya dhāmeyakṣanto na minanti svadhāvaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He hath made pathways, with the Sun to aid him, throughout the darkness that extended pathless. Mortals who yearn to worship ne'er dishonour, O Mighty God, thy Law who art Immortal.
Translated by Ralph T. H. Griffith (1896)
