3.179

有名曰：夫混元剖判、萬有參（雜）分，有既有矣，不得不無。無不自無，必因於有。所以高下相傾、有無相生，此乃自然之數。數極於是。

The Proponent of Names says: When the primal chaos divided and the myriad existences spread forth in variety, once existence came to exist, it could not but become non-existence. Non-existence does not exist by itself; it must depend on existence. Therefore, high and low tilt into one another, and existence and non-existence generate one another; this is the natural destiny. Destiny reaches its ultimate in this.
