三十輻，共一轂，當其無，有車之用。埏埴以為器，當其無，有器之用。鑿戶牖以為室，當其無，有室之用。故有之以為利，無之以為用。

Thirty spokes unite around the nave;

From their not-being (loss of their individuality)

Arises the utility of the wheel.

Mold clay into a vessel;

From its not-being (in the vessel's hollow)

Arises the utility of the vessel.

Cut out doors and windows in the house (-wall),

From their not-being (empty space) arises the utility of the house.

Therefore by the existence of things we profit.

And by the non-existence of things we are served.

【翻譯】

三十支車輪輻共同會合於中間的車輪轂，車輪轂因為中間空無，所以才有車子的用途。延展土坏以做為器具，當他中間空虛無有的時候，才有器具的用途。鑿開門窗打造宮室，當它空虛無有時，才有宮室的用途。所以實有而讓物體有了利益，虛無而讓物體有了用途。

【釋義】

《周禮·冬官考工記》：「轂也者，以為利轉也。輻也者，以為直指也。」《說文》：「轂，輻所湊也。」轂音「谷」，在車輪中央，車輻交會處，中空。輪子因轂中空而能夠轉動，讓車行走，所以說「當其無，有車之用」。轂因中空，中間虛無，而有車子的應用。

埏或作挻，長也，揉之使延長的意思。《說文》：「埴，黏土也。」

戶牖：即門窗。戶為單扇的門，牖為木窗。
