Atharva Veda 6.92: A charm to strengthen and inspirit a war-horse

Be fleet as wind, Strong Steed, when thou art harnessed; go forth as swift as thought at lndra's sending.
Let the possessors of all wealth, the Maruts, yoke thee, and Tvashtar in thy feet lay swiftness.

That speed, that lies concealed in thee, O Charger, speed granted to the hawk or wind that wandered, Therewith, Strong Steed, saving in shock of battle endowed with might by might win thou the contest.

Bearing thy body, Charger, may thy body run blessing us and winning thee protection.
May he, unswerving, to uphold the mighty, stablish his lustre as a God in heaven.
