Bhagavad Gita · Chapter 11: The Vision of the Cosmic Form
Bhagavad Gita 11.4
मन्यसे यदि तच्छक्यं मया द्रष्टुमिति प्रभो ।
योगेश्वर ततो मे त्वं दर्शयात्मानमव्ययम् ॥
manyase yadi tacchakyaṃ mayā draṣṭumiti prabho | yogeśvara tato me tvaṃ darśayātmānamavyayam ||
If you think I am able to see it, Lord, then show me your imperishable self, O master of yoga.
Modern context
Arjuna asks humbly: if you think I am able to see it. He does not demand; he leaves the judgment to the one who knows. This is a mature way to ask for something great. One recognizes that one may not be ready, and trusts the teacher to decide. Requests made this way are often the ones that are granted.
