evamuddharṣito mātrā sa rājā babhruvāhanaḥ |

The daughter of the snake, with every limb possessed of beauty, viz., Ulupi, said these words consistent with righteousness and duty unto the prince who was conversant with righteousness and duty,--'Know that I am thy mother Ulupi that am the daughter of a snake. Do thou accomplish my behest, O son, for thou wouldst then attain to great merit. Fight thy father, this foremost one of Kuru's race, this hero that is irresistible in battle. Without doubt, he will then be gratified with thee.' In this way was king Vabhruvahana incited against his sire by his (step) mother. At last, endued as he was with great energy, he made up his mind, O chief of the Bharata's, to fight Dhananjaya. Putting on his armour of bright gold and his effulgent head-gear, he ascended an excellent car which had hundreds of quivers ready on it. That car was equipt with necessaries for battle and had steeds yoked to it that were endued with the speed of the mind. It had excellent wheels and a strong Upashkara, and was adorned with golden ornaments of every kind. Raising his standard which was decorated most beautifully and which bore the device of a lion in gold, the handsome prince Vabhruvahana proceeded against his sire for battle. Coining upon the sacrificial steed which was protected by Partha, the heroic prince caused it to be seized by persons well-versed in horse-lore. Beholding the steed seized, Dhananjaya became filled with joy.
