The second consideration is that existence and non-existence are both relative. If it be said that a certain thing was brought forth from non-existence, the intent is not absolute non-existence; rather, it is meant that the former condition was non-existence in relation to the present one. For absolute non-existence cannot become existence, as it lacks the very capacity to exist. Man exists, and the mineral likewise exists, but the existence of the mineral is non-existence in relation to that of man; for when the body of man is destroyed, it becomes dust and mineral, and when dust progresses into the human world, and that inanimate body of matter becomes living, man comes into existence. Though the dust- the mineral- enjoys existence in its own station, yet in relation to man it is non-existence. Our meaning is that both exist, but the existence of dust and mineral, in relation to man, is non-existence, for when man dies he becomes dust and mineral (80:5)
