Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 38

Sanskrit:

जानन्त एव जानन्तु किं बहूक्त्या न मे प्रभो ।मनसो वपुषो वाचो वैभवं तव गोचर: ॥ ३८ ॥

ITRANS:

jānanta eva jānantukiṁ bahūktyā na me prabhomanaso vapuṣo vācovaibhavaṁ tava go-caraḥ

Translation:

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:
