14.7.6

vyāsa uvāca |
śrutvā tu pārthivasyaitatsaṃvartaḥ parayā mudā |
etāvadahamapyenaṃ kuryāmiti tadābravīt || 6 ||

Vyasa said, 'Hearing these words from the king (Marutta) Samvarta was highly gratified, and he said (addressing Marutta). 'I too am quite able to do all that.' Then, O prince, that Brahmana, raving like a lunatic, and repeatedly scolding Marutta with rude words, again accosted him thus, 'I am afflicted with a cerebral disorder, and, I always act according to the random caprices of my own mind. Why art thou bent upon having this sacrifice performed by a priest of such a singular disposition? My brother is able to officiate at sacrifices, and he has gone over to Vasava (Indra), and is engaged in performing his sacrifices, do thou therefore have thy sacrifice performed by him. My elder brother has forcibly taken away from me all my household goods and mystical gods, and sacrificing clients, and has now left to me only this physical body of mine, and, O son of Avikshit, as he is worthy of all respect from me, I cannot by any means officiate at thy sacrifice, unless with his permission. Thou must therefore go to Vrihaspati first, and taking his permission thou canst come back to me, if thou hast any desire to perform a sacrifice, and then only shall I officiate at thy sacrifice.'
