ceremonially unclean

I remember several passages in the Mosaic law that talk about ceremonial uncleanliness.  One of them was directed at women who'd given birth.  A commentary suggested that God gave that as a blessing so that the mother could have time to bond with the child, which, especially when compared to most people back then, is a heaping helping of compassion doled out by God.  But I have to wonder why He didn't just say that and instead used the word "unclean"  I have to suspect that it's intended to remind us that life wasn't always this way and should not always be this way and doesn't have to always be this way.  In the curses given by God at the fall of mankind, it was declared that childbirth would be much more painful and, prior to the fall, it was stated by God that YOU WILL SURELY DIE.  Neither Adam nor Eve died immediately after having eaten the apple (edit: fruit; Yes, I know The Bible doesn't specify what kind of fruit...), and by today's standards, Adam lived a ridiculously long time, but he did eventually die.  Simply the physical reality of death is absolutely repulsive and horrifying.  Consider the decomposition process.  There's something fascinating about it for sure, but it's not good by any means.  It looks as vacant and sad as you'd think.  And some people wax philsophicaly about "bringing a child to this cruel world"  How about bringing a child into the world that's already dying before it ever had a chance to think about it?  I think God considers all of these things.  These are not light,airy, flippant matters to Him.  

I could be mistaken in my musings.  I don't have the confidence in myself and the airtight closeness to God to declare these things like they're absolutes.  But it does seem like a worthwhile set of things to ponder, if you wanna.
