On death, it is only the physical body that becomes non-existent. The spirit, the soul, never dies. Emphasising this, Krishn says in Sankhya Yog of the Bhagwad Gita that weapons cannot shred the soul, nor can fire burn it, water cannot make it wet, nor can the wind dry it, therefore, the wise, that is, the spiritually enlightened beings, lament neither for the living nor for dead.
