devarsy-arhatsu vai satsu
rajan yad agra-pujayam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O King Yudhisthira, the demigods, many great sages and saints including even the four sons of Lord Brahma, and I myself were present at your Rajasuya sacrificial ceremony, but when there was a question of who should be the first person worshiped, everyone decided upon Lord Krsna, the Supreme Person.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This is a reference to the Rajasuya sacrifice performed by Maharaja Yudhisthira. In that meeting there was a great turmoil over selecting the best person to be worshiped first. Everyone decided to worship Sri Krsna. The only protest came from Sisupala, and because of his vehement opposition he was killed by the Supreme Personality of Godhead.
