Roman (IAST) transliteration rendered by HREEM from the edition's Devanagari; the Devanagari is the edition's own.
Like a steed neighing eager for the pasture, when he hath stepped forth from the great enclosure: Then the wind following blows upon his splendour, and, straight, the path is black which thou hast travelled.
Translated by Ralph T. H. Griffith (1896)This is the translator's rendering of the same verse where it occurs at RV 7.3.2; the wording of this text may differ in places.
