Empty spaces

We put thirty spokes to make a wheel but it is on the hole in the centre that the use of the cart hinges

We make a vessel from a lump of clay but it is the empty space within the vessel that makes it useful

We make doors and windows for a room but it is the empty spaces that make the room livable

Thus while existence has advantages, it is the void that makes it useful
