Mbh 12.338.6a

"'Bhishma continued, "Learning what the opinion was that was entertained by the deities, Vasu, moved by partiality for them, said that sacrifices should be performed with animals. At this answer, all the Rishis, endued with the splendour of the Sun, became very angry. Addressing Vasu who was seated on his car and who had (wrongly) taken up the side of the deities, they said unto him,--'Since thou hast (wrongly) taken up the side of the deities, do thou fall down from heaven. From this day, O monarch, thou shalt lose the power of journeying through the sky. Through our curse, thou shalt sink deep below the surface of the Earth.' After the Rishis had said these words, king Uparichara immediately fell down, O monarch, and went down a hole in Earth. At the command, however, of Narayana, Vasu's memory did not leave him. To the good fortune of Vasu, the deities, pained at the curse denounced on him by the Brahmanas, began to think anxiously as to how that curse might be neutralised. They said, 'This high-souled king hath been cursed for our sake. We, denizens of heaven, should unite together for doing what is good to him in return for that which he has done to us.' Having quickly settled this in their minds with the aid of reflection, the deities proceeded to the spot where the king Uparichara was. Arrived at his presence, they addressed him, saying, 'Thou art devoted to the great God of the Brahmanas (viz., Narayana). That great Lord of both the deities and the Asuras, gratified with thee, will rescue thee from the curse that has been denounced upon thee. It is proper, however, that the high-souled Brahmanas should be honoured. Verily, O best of kings, their penances should fructify.[1813] Indeed, thou hast already fallen down from the sky on the Earth. We desire, however, O best of kings, to show thee a favour in one respect. As long as thou, O sinless one, shalt dwell in his hole, so long shalt thou receive (due sustenance, through our boon)!
