Your Life is a Puzzle

I ran across this quote from Rabbi Lawrence Kushner yesterday.

"Each lifetime is the pieces of a jigsaw puzzle. For some, there are more pieces. For others, the puzzle is more difficult to assemble. But know this: you do not have within yourself all the pieces to your puzzle. Everyone carries with them at least one and probably many pieces to someone else's puzzle. Sometimes they know it; sometimes they don't. And, when you present your piece, which is worthless to you, to another, whether you know it or not, whether they know it or not, you are a messenger for the Most High."
