Gita 10.15
स्वयमेवात्मनात्मानं वेत्थ त्वं पुरुषोत्तम।
भूतभावन भूतेश देवदेव जगत्पते।।
svayam evātmanātmānaṁ vettha tvaṁ puruṣottama bhūta-bhāvana bhūteśa deva-deva jagat-pate
"You alone know Yourself by Yourself, O Supreme Person, Creator and Lord of beings, God of gods, Lord of the universe."
What This Means:
Only Krishna knows Krishna fully, 'by Yourself, through Yourself' (atmanatmanam). Others can know aspects, but complete self-knowledge belongs only to the One. He is creator, lord, god of gods, universe-master.
Going Deeper:
Self-knowledge at the ultimate level is unique. Finite minds can approach but not encompass the infinite. Yet this isn't discouraging, it means there's always more to discover.
How To Apply This:
Don't expect to 'figure out' the Divine completely. That's not failure, it's the nature of the relationship. Infinite depth means infinite exploration.
