SB 10.14.38
jananta eva janantu
kim bahuktya na me prabho
manaso vapuso vaco
vaibhavam tava go-carah
Translation:
There are people who say, “I know everything about Krsna.” Let them think that way. As far as I am concerned, I do not wish to speak very much about this matter. O my Lord, let me say this much: As far as Your opulences are concerned, they are all beyond the reach of my mind, body and words.
Purport:
