Lao Tzu

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 for a house, 

but it is the inner space

that makes it livable.

We work with being, 

but non-being is what we use.

Hamlet

"There is nothing either good or bad, 

    but thinking makes it so."

~W. Shakespeare
