jānanta eva jānantu kiṁ bahūktyā na me prabho manaso vapuṣo vāco vaibhavaṁ tava gocaraḥ
“ ‘There are people who say, “I know everything about Kṛṣṇa.” 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
This is a quotation from Śrīmad-Bhāgavatam (10.14.38), spoken by Lord Brahmā after he had stolen Lord Kṛṣṇa’s calves and cowherd boys and Kṛṣṇa had exhibited His transcendental opulence by re-creating all the stolen calves and cowherd boys by His viṣṇu-mūrti expansions. After he had seen this, Brahmā offered the above prayer.
