A cup is made
of bottom and sides --
but its use
lies in emptiness.

A house is made
of roof and walls --
but its use
lies in emptiness.

The greater the road,
The greater the emptiness.
Something about nothing
makes us able to use
what's there by what isn't.

So, tell me, please,
which you like best:
being ...
or nothingness?

-- Lao Tzu
