Bhagavad Gita, Chapter 11, Verse 46

Diademed, bearing a mace and a discus, You I desire to see as before. Assume that same four-armed Form, O You of thousand arms, of universal Form.

Even after everything shown, Arjun asks for something smaller, more real, more familiar to actually hold onto.

Requesting the four-armed form instead of the boundless one shows what Arjun genuinely needs right now isn't more scale, it's something he can actually relate to. Real comfort matters here as much as real awe did before.
