This is a favorite of a dear friend of mine, I've come to appreciate it more since when she first shared it with me. I was tempted to write some commentary on it but I'll let it speak for itself:
Someone who goes with half a loaf of bread
to a small place that fits like a nest around him,
someone who wants no more, who's not himself
longed for by anyone else,
He is a letter to everyone. You open it.
It says, Live.
