The second chapter is called Sankhya yoga but actually it deals entirely with Vedanta. The eternal nature of the atman and the ephemeral mature of the body is revealed to Arjuna. "The atman is eternal, immortal, never born and therefor can never die. It is pure consciousness and pure existence. That which is existent can never cease to exist. This is one of the laws of physics - energy can never be destroyed. it can only change its form. One body falls and the jivatman flits to another body through which it can best fulfill its destiny.
