RV 5.45.1
विदा दिवो विष्यन्न् अद्रिम् उक्थैर् आयत्या उषसो अर्चिनो गुः । अपावृत व्रजिनीर् उत् स्वर् गाद् वि दुरो मानुषीर् देव आवः ॥
vidā divo viṣyann adrim ukthair āyatyā uṣaso arcino guḥ | apāvṛta vrajinīr ut svar gād vi duro mānuṣīr deva āvaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Bards of approaching Dawn who know the heavens are come with hymns to throw the mountain open. The Sun hath risen and open the stable portals: the doors of men, too, hath the God thrown open.
Translated by Ralph T. H. Griffith (1896)
