SB 10.66.2
tvam vasudevo bhagavan
avatirno jagat-patih
iti prastobhito balair
mena atmanam acyutam
Translation:
Paundraka was emboldened by the flattery of childish men, who told him, “You are Vasudeva, the Supreme Lord and master of the universe, who have now descended to the earth.” Thus he imagined himself to be the infallible Personality of Godhead.
Purport:
Paundraka foolishly accepted the flattery of ignorant persons.
