Bhagavad Gita
Chapter 4 · Verse 34
तद्विद्धि प्रणिपातेन परिप्रश्नेन सेवया। उपदेक्ष्यन्ति ते ज्ञानं ज्ञानिनस्तत्त्वदर्शिनः॥
tad viddhi praṇipātena paripraśnena sevayā, upadekṣyanti te jñānaṁ jñāninas tattva-darśinaḥ
Real understanding tends to open up through humility and honest questions, not certainty. And it's often passed on person to person.
Approach wisdom with humility, honest questions, and an open hand.
