Dîrghatamâ settled himself in the house of his brother, leading a life of total celibacy. Whilst so dwelling, he learnt from a bull, the dharma of the cattle, that of promiscuous intercourse without regard to relationship. He was supported by his brother and uncle Sometime after, an ox happened to go there of his own accord, and began to feast himself on the Kuśa grass, planted there for sacrificial purposes, when Dîrghatamâ caught him by the horns.—43-45.
