When I read this I got a distinct "fallen from Grace" vibe. The angels cast out from heaven...cut off from the grace of God. A severing of the umbilical cord type of thing.

Perfecting a creation to the point it can self govern, does it have to go through a period of time where the creation is cast off to create it's on it's own and tend it's own garden before it can again join the family...

interesting.... if not prophetic than a repeating of a pattern
