Mbh 13.156.8a

"'"The god of wind said, 'Then Chyavana, taking the Aswins with him, commenced a great religious rite for their benefit. The gods all became stupefied by Chyavana with his Mantras. Beholding that feat commenced by Chyavana, Indra became incensed with wrath. Taking up a huge mountain he ran against that Rishi. The chief of the deities was also armed with the thunderbolt. Then the illustrious Chyavana, endued with penances, cast an angry glance upon Indra as he advanced. Throwing a little water at him, he paralysed the chief of the deities with his thunderbolt and mountain. As the result of the religious rite he had commenced, he created a terrible Asura hostile to Indra. Made of the libations he had poured on the sacred fire, that Asura was called Mada, of mouth gaping wide. Even such was the Asura that the great ascetic created with the aid of Mantras. There were a thousand teeth in his mouth, extending for a hundred yojanas. Of terrible mien, his fangs were two hundred yojanas in length. One of his cheeks rested on the earth and the other touched the heavens. Indeed, all the gods with Vasava seemed to stand at the root of that great Asura's tongue, even as fishes when they enter into the wide open mouth of a leviathan. While standing within the mouth of Mada, the gods held a quick consultation and then addressing Indra, said, "Do thou soon bend thy head in reverence unto this regenerate personage! Freed from every scruple, we shall drink Soma with the Aswins in our company!" Then Sakra, bowing down his head unto Chyavana, obeyed his behest. Even thus did Chyavana make the Aswins drinkers of Soma with the other gods. Calling back Mada, the Rishi then assigned him the acts he was to do. That Mada was commanded to take up his residence in dice, in hunting, in drinking, and in women. Hence, O king, those men that betake themselves to these, meet with destruction, without doubt. Hence, one should always cast off these faults to a great distance.
