vārṣṇeyena bhavennūnaṃ vidyā saivopaśikṣitā |
tenāsya rathanirghoṣo nalasyeva mahānabhūt || 32 ||

"Vrihadaswa continued, 'And, O king, after Rituparna had gone away with Varshneya, Vahuka took the car to the stables. And there freeing the steeds, and tending them according to rule, and soothing them himself, sat down on a side of the car. Meanwhile, the princess of Vidharva, Damayanti, afflicted with grief, having beheld the royal son of Bhangasura, and Varshneya of the Suta race, and also Vahuka in that guise, asked herself, 'Whose is this car-rattle? It was loud as that of Nala, but I do not see the ruler of the Nishadhas. Certainly, Varshneya hath learnt the art from Nala, and it is for this the rattle of the car driven by him hath been even like that of Nala. Or, is Rituparna equally skilled with Nala so that the rattle of his car seemeth to be like that of Nala?' And reflecting thus, O monarch, the blessed and beauteous girl sent a female messenger in search of Nishada."
