Bhagavad Gita, Chapter 11, Verse 16

I see You of boundless form on every side with manifold arms, stomachs, mouths and eyes; neither the end nor the middle, nor also the beginning of You do I see, O Lord of the universe, O Universal Form.

Arjun searches for an edge to this vision and finds none, real, total boundlessness instead.

Countless arms, faces, and eyes refuse to resolve into anything with a clear outline. What Arjun describes here is the real experience of meeting something without limit.
