SB 7.15.78
sri-suka uvaca
iti devarsina proktam
nisamya bharatarsabhah
pujayam asa supritah
krsnam ca prema-vihvalah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami said: Maharaja Yudhisthira, the best member of the Bharata dynasty, thus learned everything from the descriptions of Narada Muni. After hearing these instructions, he felt great pleasure from within his heart, and in great ecstasy, love and affection, he worshiped Lord Krsna.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
It is natural that when someone belonging to one’s family circle is understood to be very great, one becomes ecstatic in love, thinking, “Oh, such a great personality is our relative!” When Sri Krsna, who was already known to the Pandavas, was further described by Narada Muni to be the Supreme Personality of Godhead, naturally the Pandavas were amazed, thinking, “The Supreme Personality of Godhead is with us as our cousin!” Certainly their ecstasy was extraordinary.
