I came across this poem... I think it's worth a ponder...

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 go this way and that.
Trying to assemble the myriad parts.

But know this. No one has within themselves
All the pieces to their 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
to another, whether you know it or not,
whether they know it or not,
you are a messenger from the Most High

by Rabbi  Lawrence Kuschner
