Humans are incomplete because they live inside their self-made mind world that overlaps the world. That is karma, habits, and body. If you throw away the self and the incomplete world, which is karma, habits, and body, go to the existent world of Truth, and are reborn, that land is the existent world of Truth. It is the land where you can live eternally without death. You must go to this land and while you are alive and live forever.
