Bhagavad Gita, Chapter 8, Verse 22

And that Supreme Purusha is attainable, O son of Prithâ, by whole-souled devotion to Him alone, in whom all beings dwell, and by whom all this is pervaded.

Being present everywhere and actually being known turn out to be two genuinely different things.

This makes a real, important distinction. Closeness alone doesn't guarantee real understanding, something specific, genuine devotion, is described as the actual key that makes that ever-present nearness knowable.
