The body dies, but the spirit that transcends it cannot be touched by death.

Who am I? Not the body, because it is decaying; not the mind, because the brain will decay with the body; not the personality, nor the emotions, for these also will vanish with death.

That which comes and goes, rises and sets, is born and dies is the ego. That which always abides, never changes, and is devoid of qualities is the Self.

I am not the perishable body, but the eternal Self.

Concentration of the mind is in a way common to both Knowledge and Yoga. Yoga aims at union of the individual with the universal, the Reality. This Reality cannot be new. It must exist even now, and it does exist.

As instruments for knowing the objects, the sense organs are outside, and so they are called outer senses; and the mind is called the inner sense because it is inside. But the distinction between inner and outer is only with reference to the body; in truth, there is neither inner nor outer. The mind's nature is to remain pure like ether.
