9.35.3

tatra dharmaparo hyāsīttritaḥ sa sumahātapāḥ |
kūpe ca vasatā tena somaḥ pīto mahātmanā || 3 ||

Vaishampayana said, "Baladeva (as already said), proceeded next to the tirtha called Udapana in the Sarasvati, that had formerly been the residence, O king, of the illustrious (ascetic) Trita. Having given away much wealth and worshipped the Brahmanas, the hero having the plough for his weapon bathed there and became filled with joy. Devoted to righteousness, the great ascetic Trita had lived there. While in a hole, that high-souled one had drunk the Soma juice. His two brothers, dashing him down into that pit, had returned to their home. That foremost of Brahmanas, Trita, had thereupon cursed them both."
