The main cause of all bondage is ignorance. Man is not wicked by his own nature — not at all. His nature is pure, perfectly holy. Each man is divine. Each man that you see is a God by his very nature. This nature is covered by ignorance, and it is ignorance that binds us down. Ignorance is the cause of all misery.
Ignorance is the cause of all wickedness; and knowledge will make the world good. Knowledge will remove all misery. Knowledge will make us free. This is the idea of Jnana-Yoga: knowledge will make us free! What knowledge? Chemistry? Physics? Astronomy? Geology? They help us a little, just a little. But the chief knowledge is that of your own nature. "Know thyself." You must know what you are, what your real nature is. You must become conscious of that infinite nature within. Then your bondages will burst. (IX, 214)
