The poet, to those who seek him: If you ask where he is, the one whose hands bear the white conch that calls his servants to him and the sacred discus of fierce flame, come, I shall tell you a little sign: there are those who saw him standing at the front, [as charioteer,] on the chariot with white horses and the victorious monkey banner, a wily ally to the army, conducting the Bhārata war.
