 Beings depend on wu in coming into existence, in becoming what they are. Affairs on account of wu come to fruition and become what they are. Now, one tries to speak about wu, but no words could describe it; name it, but it has no name; look at it, but it does not have any form; listen to it, but it does not give any sound. Then, indeed, it is clear that the Dao is complete (quan). Thus, it can bring forth sounds and echoes; generate qi energies and things; establish form and spirit; and illuminate light and shadows. What is dark obtains its blackness from it; what is plain obtains its whiteness from it. The carpenter’s square is able to make a square because of it; the compass is able to make a circle because of it. The round and the square obtain their form, but that which gives them their form itself does not have any form. The white and the black obtain their name, but that which gives them their name itself does not have any name.
