Bhagavad Gita, Chapter 11, Verse 14

Then Dhananjaya, filled with wonder, with his hair standing on end, bending down his head to the Deva in adoration, spoke with joined palms.

Arjun's own real, physical response is described before he manages to say a single word.

Awe here shows up in the body first, trembling, bowing, before it becomes language. That real, involuntary reaction says as much as anything Arjun goes on to speak.
