athābravītsadasyāṃstu gautamo munisattamān |
āvayorvyāhṛtaṃ praśnaṃ śṛṇuta dvijapuṃgavāḥ |
vainyo vidhātetyāhātriratra naḥ saṃśayo mahān || 19 ||

"Markandeya continued, 'While those two men were thus disputing in the presence of the Munis, who were engaged in Vainya's sacrifice the latter enquired, 'What is the matter with them, that maketh them talk so vociferously?' Then the very pious Kasyapa learned in all religious lore, approaching the disputants asked them what was the matter. And then Gautama, addressing that assembly of great Munis said, 'Listen, O great Brahmanas, to the point in dispute between us. Atri hath said that Vainya is the ruler of our destinies; great is our doubt on this point.'
