"The thirty spokes converge at one hub, But the utility of the cart is a function of the nothingness (wn) inside the hub. We throw clay to shape a pot, But the utility of the clay pot is a function of the nothingness inside it. We bore out doors and windows to make a dwelling, But the utility of the dwelling is a function of the nothingness inside it. Thus, it might be something (you) that provides the value, But it is nothing that provides the utility."
