Poem of the day: Lao-Tzu on non-being

We join spokes together in a wheel
but it is the center hole
that makes the wagon move
We shape clay into a pot
but it is the emptiness inside
that holds whatever we want
We hammer wood into a house
but it is the inner space
that makes it livable
We work with being
But non-being is what we use.

(Lao Tzu)

... this is one that saves me again and again.
