Mbh 2.13.2

Vaisampayana said,--“King Yudhishthira, then, that foremost of speakers, summoning together his counsellors and brothers, asked them repeatedly about the Rajasuya sacrifice. Those ministers in a body, thus asked by the wise Yudhishthira desirous of performing the sacrifice, then told him these words of grave import,--‘One already in possession of a kingdom desireth all the attributes of an emperor by means of that sacrifice which aideth a king in acquiring the attributes of Varuna. O prince of Kuru race, thy friends think that as thou art worthy of the attributes of an emperor, the time is even come for thee for the performance of the Rajasuya sacrifice. The time for the performance of that sacrifice in which Rishis of austere vows kindle six fires with mantras of the Sama Veda, is come for thee in consequence of thy Kshatriya possessions. At the conclusion of the Rajasuya sacrifice when the performer is installed in the sovereignty of the empire, he is rewarded with the fruits of all sacrifices including the Agnihotra. It is for this that he is called the conqueror of all. Thou art quite able, O strong-armed one, to perform this sacrifice. All of us are obedient to thee. Soon will you be able, O great king, to perform the Rajasuya sacrifice. Therefore, O great king, let thy resolution be taken to perform this sacrifice without further discussion. Thus, spoke unto the king all his friends and counsellors separately and jointly. And, O king, Yudhishthira that slayer of all enemies, having heard these virtuous, bold, agreeable and weighty words of theirs, accepted them mentally. And having heard those words of his friends and counsellors, and knowing his own strength also, the king, O Bharata, repeatedly thought over the matter. After this the intelligent and virtuous Yudhishthira, wise in counsel, again consulted with his brothers, with the illustrious Ritwijas about him, with his ministers and with Dhaumya and Dwaipayana and others.
