Each lifetime is the pieces of a jigsaw puzzle.
For some there are more pieces.
For others the puzzle is more difficult to assemble.
Some seem to be born with a nearly completed puzzle.
And so it goes.
Souls going this way and that.
Trying to assemble the myriad parts.
But know this, no one has within themselves, all of the pieces to their puzzle.
Like before the days when they used to seal jigsaw puzzles in cellophane.
Insuring that all the pieces were there.
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 from the most high.
-Rabbi Lawrence Kushner
