One man believes he is the slayer, another believes he is the slain. Both are ignorant; there is neither slayer nor slain. You were never born; you will never die. You have never changed; you can never change. Unborn, eternal, immutable, immemorial, you do not die when the body dies. Realizing that which is indestructible, eternal, unborn, and unchanging, how can you slay or cause another to be slain? As a man abandons his worn-out clothes and acquires new ones, so when the body is worn out a new one is acquired by the Self, who lives within. The Self cannot be pierced with weapons or burned with fire; water cannot wet it, nor can the wind dry it. The Self cannot be pierced or burned, made wet or dry. It is everlasting and infinite, standing on the motionless foundation of eternity. The Self is unmanifested, beyond all thought, beyond all change. Knowing this, you should not grieve.

(The Bhagavat Gita)
