Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The richly-coloured Dawns have mounted eastward, like pillars planted at our sacrifices, And, flushing far, splendid and purifying, unbarred the portals of the fold of darkness.
Translated by Ralph T. H. Griffith (1896)
