Read the following excerpt from the Bhagavad-Gita.

"For the soul there is neither birth nor death at any time. He has not come into being, does not come into being, and will not come into being. He is unborn, eternal (unending), ever-existing and primeval (ancient and original). He is not slain (killed) when the body is slain."

What central part of Hinduism does this quote illustrate?
