सर्वमेतदृतं मन्ये यन्मां वदसि केशव ।न हि ते भगवन्व्यक्तिं विदुर्देवा न दानवाः॥
sarvam etad ṛtaṃ manye yan māṃ vadasi keśavana hi te bhagavan vyaktiṃ vidur devā na dānavāḥ
Word by word
The verse says
I accept all of this as true, Krishna, everything you have told me. Neither the gods nor the demons know how you show yourself, Lord.
In plain words
He says plainly that he accepts it, and in the same breath says that nobody understands it.
Those two are usually in tension. Here they are not.
Arjuna is not claiming to have worked it out. He is saying he is persuaded by somebody he trusts, about something he cannot verify.
Where you've felt this · at work
The engineer who maintains the lift in your building tells you the cable will hold ten times the load. You have no way to check this and would not know what to check. You get in the lift twice a day, which is the only form your agreement with him takes.
Going deeper
Accepting something you cannot verify is ordinary, and the verse neither dresses it up nor apologises for it.
Arjuna is explicit about both halves. He believes it. He also states that the gods themselves do not grasp it, which means he is not claiming to have grasped it either. What he has is a particular kind of confidence: not in a conclusion he reached, but in the person telling him.
It would be easy to treat that as a weakness in the argument. It is more honest to notice that almost everything anybody acts on has this shape. Most of what you are confident about today arrived from somebody who knew more than you, and you took it.
So the question the verse quietly raises is not whether you are willing to believe things you cannot check — you already do, constantly — but how you choose who to take them from.
