Mbh 1.3.5

“About this time there was a Rishi, Ayoda-Dhaumya by name. And Ayoda-Dhaumya had three disciples, Upamanyu, Aruni, and Veda. And the Rishi bade one of these disciples, Aruni of Panchala, to go and stop up a breach in the water-course of a certain field. And Aruni of Panchala, thus ordered by his preceptor, repaired to the spot. And having gone there he saw that he could not stop up the breach in the water-course by ordinary means. And he was distressed because he could not do his preceptor’s bidding. But at length he saw a way and said, ‘Well, I will do it in this way.’ He then went down into the breach and lay down himself there. And the water was thus confined.
