Without knowing the Knower, all the knowledge that one gathers cannot be valid.

The world is illusory, Only Brahman is real, Brahman is the world

From where does this "I" arise? Seek for it within; it then vanishes. This is the pursuit of wisdom. When the mind unceasingly investigates its own nature, it transpires that there is no such thing as mind. This is the direct path for all. The mind is merely thoughts. Of all thoughts the thought "I" is the root.

Call it by any name, God, Self, the Heart, or the Seat of Consciousness, it is all the same.

When one makes the mind stick to one thought, the mind becomes rock-steady and the energy is conserved.

You may go on reading any number of books on Meditation. They can only tell you ‘Realize the Self’. The Self cannot be found in books. You have to find it for yourself in yourself.

Your duty is to be, and not to be this or that. I Am That I Am sums up the whole truth; the method is summarized in Be Still.
