Bhagavad Gita, Chapter 7, Verse 26

I know, O Arjuna, the beings of the whole past, and the present, and the future, but Me nobody knows.

Being fully known and fully knowing turn out to be two genuinely different, asymmetric things here.

This names a real imbalance directly. Complete knowledge flows one direction in this picture, while being fully known in return is described as something that essentially doesn't happen, at least not through ordinary means.
