Mbh 14.9.25

"'"Agni said, 'Dost thou, O Mahendra, remember that in olden times when the sage Chyavana officiated at the sacrifice of Saryati with the twin gods Aswins and himself appropriated the Soma offering alone, thou wert filled with wrath, and when bent upon preventing Saryati's sacrifice, thou didst violently strike Chyavana with thy thunderbolt? But that Brahmana, O Purandara, giving way to passion, was able by the power of his devotions to seize and hold fast by hand with thy thunder-bolt in it. And in a rage, he again created a terrible looking enemy of thine, the Asura named Mada assuming all shapes, on beholding whom thou didst shut thine eyes with fear, whose one huge jaw was placed on earth, and the other extended to the celestial regions, and who looked terrible with his thousand sharp teeth extending over a hundred Yojanas, and had four prominent ones thick-set, and shining like a pillar of silver, and extending over two hundred Yojanas. And when grinding his teeth he pursued thee with his terrible and uplifted pike with the object of killing thee. Thou on beholding that terrible monster, presented a (pitiful) spectacle to all the by-standers. Then, O slayer of Danavas, overcome with fear of the monster, with thy hands clasped in supplication, thou didst seek the protection of the great sage. The might of Brahmanas, O Sakra, is greater than that of the Kshatriyas. None are more powerful than Brahmanas and knowing duly, as I do, the power of Brahmanas, I do not, O Sakra, desire to come in conflict with Samvarta.'"'"
