Verse 11
Wu is nothingness, emptiness, non-existence
Thirty spokes of a wheel all join at a common hub
yet only the hole at the centre
allows the wheel to spin
Clay is moulded to form a cup
yet only the space within
allows the cup to hold to hold water
Walls are joined to make a room
yet only by cutting out a door and a window
can one enter the room and live there
Thus, when a thing has existence alone
it is mere dead-weight
Only when it has wu, does it have life
