There is that which is unborn, unoriginated, unmade, unformed, and unconditioned.
If there were no unborn, unoriginated, unmade, and unconditioned self, then escape from what is born, originated, made, formed, and conditioned could not be known.
However, because there exists that which is unborn, unoriginated, unmade, unformed, and unconditioned self, an escape from that which is born, made, defiled, contaminated, and conditioned non-self in the world is known.
Within the born, made, formed, and conditioned non-self, there exists the unborn, unoriginated, unmade, unformed, and unconditioned self.
If the unborn, unoriginated, unmade, unformed, and unconditioned self did not exist, liberation from the born, originated, made, formed, and conditioned non-self could not be possibly known.
Because the unborn, unoriginated, unmade, unformed, and unconditioned self exists, liberation from the formed, fabricated, defiled, contaminated, and conditioned non-self is possible.
