Self is everywhere, shining forth from all beings, vaster than the vast, subtler than the most subtle, unreachable, yet nearer that breath, than heartbeat. Eye cannot see it, ear cannot hear it nor tongue utter it; only in deep absorption can the mind, grown pure and silent, merge with the formless truth. As soon as you find it, you are free; you have found yourself; you have solved the great riddle; your heart is forever at peace. Whole, you enter the Whole. Your personal self returns to its radiant, intimate, deathless source.
The All-knowing Self was never born, nor will it die. Beyond cause and effect, this self is eternal and immutable. When the body dies, the Self does not die. If the slayer believes that he can kill and the slain believes that he can be killed, neither knows the truth. The eternal Self slays not, nor is ever slain. Upanishads
