Ponder Points

I asked this of Katie yesterday when we were imagining heaven...

Are there mirrors in heaven?

and something else I've been wondering, especially with all this "pope talk" lately...

What does it mean to "bless" someone? Can people "bless" other people? What exactly happens when someone "blesses" me?

* * UPDATE * *

Phisch poses another ponderable in the comments:

Are there shadows in heaven?

There is some great discussion going on in the comments so join in the fun!
