Bhagavad Gita, Chapter 11, Verse 3

So it is, O Lord Supreme! as You have declared Yourself. Still I desire to see Your Ishvara-Form, O Purusha Supreme.

Belief alone isn't enough here, Arjun wants to see the real thing for himself.

Accepting Krishna's words as true doesn't stop Arjun from asking for direct, firsthand experience. Real conviction and real curiosity are shown working together, not standing in for each other.
