Bhagavad Gita, Chapter 11, Verse 13

There in the body of the God of gods, the son of Pându then saw the whole universe resting in one, with its manifold divisions.

The whole universe, real and complete, is described as visible all at once in a single place.

This isn't a partial glimpse, it's the totality of creation held together and seen together. Real scale is made literal here, not just implied.
