Hello everybody, I should find the original version of a famous quote of the famous philosopher 老子(Laozi). an english version of that sentence is: We need the clay to make a vase, but all we need is the empity space inside. or, another english translation, We impaste the clay to make a jar, but in its "not-being" we find the utility of the jar. Does anybody knows which is the original chinese version of this sentence? It must be written in the 道德經 (Dàodéjīng)...谢谢!!
