Sounds like this quote (posted elsewhere in this thread):

Thirty spokes share the wheel's hub;

It is the center hole that makes it useful.

Shape clay into a vessel;

It is the space within that makes it useful.

Cut doors and windows for a room;

It is the holes which make it useful.

Therefore profit comes from what is there;

Usefulness from what is not there.

Tao Te Ching - Lao Tzu - chapter 11

It's that same quote translated by Google instead of by a human.
