Srimad Bhagavatam Canto 10, Chapter 14, Text 39

SB 10.14.39

anujanihi mam krsna
sarvam tvam vetsi sarva-drk
tvam eva jagatam natho
jagad etat tavarpitam
My dear Krsna, I now humbly request permission to leave. Actually, You are the knower and seer of all things. Indeed, You are the Lord of all the universes, and yet I offer this one universe unto You.
In his Krsna, the Supreme Personality of Godhead, Srila Prabhupada has quoted Lord Brahma as follows: “My dear Lord, although You are the Supreme Lord of all creation, I sometimes falsely think that I am the master of this universe. I may be master of this universe, but there are innumerable universes, and there are also innumerable Brahmas who preside over these universes. But actually You are the master of them all. As the Supersoul in everyone’s heart, You know everything. Please, therefore, accept me as Your surrendered servant. I hope that You will excuse me for disturbing You in Your pastimes with Your friends and calves. Now if You will kindly allow me, I will immediately leave so You can enjoy Your friends and calves without my presence.”
The words sarvam tvam vetsi sarva-drk are very significant here. Lord Krsna knows everything and sees everything, and therefore Lord Brahma did not need to remain in Vrndavana to maintain his personal loving contact with the Lord. In fact, as the creator of the universe, Lord Brahma was somewhat out of place in the simple, blissful atmosphere of Vrndavana, where Lord Krsna was exhibiting His supreme opulences in herding cows, enjoying picnics, playing games, and so on.
Upon seeing the intense love the residents of Vrndavana had for Lord Krsna, Brahma felt unqualified to remain there. He was not eager to give up the Lord’s association, but he felt it better to return to his personal devotional service in Brahmaloka. Somewhat embarrassed and unhappy over his foolish attempt at bewildering the Lord, Brahma preferred to resume his transcendental loving service rather than try to enjoy the Lord’s presence.
