"Vyasa said, 'The ancient legend of Vrihaspati and the wise Marutta is cited in this connection. On hearing of the compact made by Angira's son Vrihaspati with the lord of the gods (Indra), king Marutta made the necessary preparations for a great sacrifice. The eloquent grandson of Karandhama, (Marutta) having conceived the idea of a sacrifice in his mind, went to Vrihaspati and addressed him thus, 'O worshipful ascetic, I have intended to perform the sacrifice which thou didst propose to me once on a previous occasion and in accordance with thy instructions, and I now desire to appoint thee as officiating priest in this sacrifice, the materials whereof have also been collected by me.--O excellent one, thou art our family priest, therefore do thou take those sacrificial things and perform the sacrifice thyself.'
