tataḥ sūryāya japyānte karṇaḥ svapnaṃ nyavedayat || 17 ||

Vaisampayana continued, "Having said this, the thousand-rayed deity suddenly vanished away. The next day, after having told his prayers, Karna related his dream unto the Sun. And Vrisha related unto him the vision he had seen, and all that had passed between them in the night. Thereupon, having heard everything, that enemy of Swarbhanu, that lord, the resplendent and divine Surya, said unto him with a smile, 'It is even so!' Then Radha's son, that slayer of hostile heroes, knowing all about the matter, and desirous of obtaining the dart, remained in expectation of Vasava."
