मन्यसे यदि तच्छक्यं मया द्रष्टुमिति प्रभो।योगेश्वर ततो मे त्वं दर्शयाऽत्मानमव्ययम्॥
manyase yadi tac chakyaṃ mayā draṣṭum iti prabhoyogeśvara tato me tvaṃ darśayātmānam avyayam
Word by word
The verse says
If you think I am able to see it, lord of yoga, then show me yourself, you who do not pass away.
In plain words
The condition he attaches is about himself, not about the request.
Manyase yadi tac chakyaṃ mayā draṣṭum — if you think it can be seen by me.
He is asking somebody who knows him better than he knows himself to make the judgement.
Where you've felt this · in health
You ask a physiotherapist whether you are ready to run again, and you mean it as a real question. You could decide for yourself and you would get it wrong in one direction or the other. She has watched you walk across the room, which you cannot do.
Going deeper
Letting somebody else judge your readiness is unusual, and it is the detail that makes this request different from a demand.
Arjuna wants the vision. He does not claim he can handle it. He puts that question to the one person in a position to answer it and leaves it there. That is not humility as a performance — it is an accurate account of where the relevant knowledge sits.
The next verses will show he was right to be unsure. He is given a new eye before he can see anything, and even then he comes apart.
What this models is a specific kind of asking. There are things worth wanting that you are not in a position to assess your own fitness for. Asking anyway, and letting somebody who can see you decide, is not weakness. It is the only way the question gets answered correctly.
