That’s very profound.  I fully believe no action, event or person is ‘self contained.’  Meaning everything that happens is part of a bigger, beautiful picture.  We’re just too close to it right now to see the whole tapestry.

What I like about your sentence, is that since everyone matters and everyone has their own part to play, there’s no room for jealousy or drama or a sense of someone taking from you.  We each have what we’re meant to have, and playing the part we’re meant to play.  We’re perfect for the specific role we’re playing.
