Unborn, Imperishable, Unconquerable, Limitless, ect...All words that could be used to describe God. When a person realizes they are the physical manifestation of God they understand that death and suffering is something that happens to the body, not the soul that is God. Many religions do an injustice to people by teaching them God is on the outside of them instead of within. Non duality is moving beyond the duality that the physical universe is made up of. Duality are the physical laws that make physical reality possible. We are separate from this. The physical is nothing more than the vehicle God (us) travels around in. When you have this "knowing" you move beyond fear while accepting fear as necessary. You actively support your life while understanding you are both par of it and separate from it. Non duality is a form of duality as the duality made up of duality and non duality. Layers upon and within layers.
