RV 4.6.5
परि त्मना मितद्रुर् एति होताग्निर् मन्द्रो मधुवचा ऋतावा । द्रवन्त्य् अस्य वाजिनो न शोका भयन्ते विश्वा भुवना यद् अभ्राट् ॥
pari tmanā mitadrur eti hotāgnir mandro madhuvacā ṛtāvā | dravanty asya vājino na śokā bhayante viśvā bhuvanā yad abhrāṭ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Agni himself, the Priest, with measured motion, goes round, with sweet speech, cheerful, true to Order. His fulgent flames run forth like vigorous horses; all creatures are affrighted when he blazes.
Translated by Ralph T. H. Griffith (1896)
