Mbh 9.50.1a

Vaishampayana said, "In that tirtha lived in days of yore a Rishi of virtuous soul, named Asita-Devala, observant of the duties of Domesticity. Devoted to virtue, he led a life of purity and self-restraint. Possessed of great ascetic merit, he was compassionate unto all creatures and never injured anyone. In word, deed, and thought, he maintained an equal behaviour towards all creatures. Without wrath, O monarch, censure and praise were equal to him. Of equal attitude towards the agreeable and the disagreeable, he was, like Yama himself, thoroughly impartial. The great ascetic looked with an equal eye upon gold and a heap of pebbles. He daily worshipped the gods and guests, and Brahmanas (that came to him). Ever devoted to righteousness, he always practised the vow of brahmacarya. Once upon a time, an intelligent ascetic, O monarch, of the name of Jaigishavya, devoted to Yoga and rapt in meditation and leading the life of a mendicant, came to Devala's asylum. Possessed of great splendour, that great ascetic, ever devoted to Yoga, O monarch, while residing in Devala's asylum, became crowned with ascetic success. Indeed, while the great Muni Jaigishavya resided there, Devala kept his eyes on him, never neglecting him at any time. Thus, O monarch, a long time was passed by the two in days of yore. On one occasion, Devala lost sight of Jaigishavya, that foremost of ascetics. At the hour, however, of dinner, O Janamejaya, the intelligent and righteous ascetic, leading a life of mendicancy, approached Devala for soliciting alms. Beholding that great ascetic re-appear in the guise of a mendicant, Devala showed him great honour and expressed much gratification. And Devala worshipped his guest, O Bharata, according to the measure of his abilities, after the rites laid down by the Rishis and with great attention for many years. One day, however, O king, in the sight of that great Muni, a deep anxiety perturbed the heart of the highsouled Devala.
