Just as the fire is the direct cause for cooking, so without Knowledge no emancipation can be had. Compared with all other forms of discipline Knowledge of the Self is the one direct means for liberation.
Action cannot destroy ignorance, for it is not in conflict with or opposed to ignorance. Knowledge does verily destroy ignorance as light destroys deep darkness.
The Soul appears to be finite because of ignorance. When ignorance is destroyed the Self which does not admit of any multiplicity truly reveals itself by itself: like the Sun when the clouds pass away.
Constant practice of knowledge purifies the Self (‘Jivatman’), stained by ignorance and then disappears itself – as the powder of the ‘Kataka-nut’ settles down after it has cleansed the muddy water.
Atma Bodha of Adi Shankaracharya
