Translation: 
When I finished performing mystic yoga for one thousand years, you asked me upon whom I was meditating. Now, here is that Supreme Person to whom time has no entrance and who the Vedas cannot understand.
Purport: 

Eternal time enters anywhere and everywhere, but it cannot enter the kingdom of god. Nor can the Vedas understand the Supreme Personality of Godhead. This is an indication of the Lord’s being omnipotent, omnipresent and omniscient.
