Religion is the result of imagination. A response to fear of death and necessity for society to control its darker elements.
If then we are being asked to align an imaginative landscape, a heaven or hell, reincarnation to whatever motivates us to not despair or to do no harm to those around, reincarnation, being born again, not for the sake of living again, because living is hard work, but to continue to contribute to the cycle in a small way motivates me.
To be small, one of seven billion humans, as the universe lopes forward.
Abra believes she will continue to live through the grass (and a tree her imagination shows her is near her grave when she thinks of dying) when she is buried.
Reincarnation in this sense still requires an imagination, one coupled to the logic of a physical body. I love that.
