SB 10.28.9
sri-suka uvaca
evam prasaditah krsno
bhagavan isvaresvarah
adayagat sva-pitaram
bandhunam cavahan mudam
Translation:
Sukadeva Gosvami said: Thus satisfied by Lord Varuna, Sri Krsna, the Supreme Personality of Godhead, Lord of lords, took His father and returned home, where their relatives were overjoyed to see them.
Purport:
In this pastime, Lord Krsna gives a sublime demonstration of His position as the Supreme Lord of all lords. Varuna, the demigod of the seas, is most powerful, yet he was happy to worship even Lord Krsna’s father, what to speak of Krsna Himself.
