摩訶止觀 10.39

10.39

若計自然作惡者：謂萬物自然，恣意造惡，終歸自然。斯乃背無欲而恣欲，違於妙而就麁。如莊周斥仁義，雖防小盜，不意大盜揭仁義以謀其國。本以自然息欲，乃揭自然而為惡，此義可知也。

As for those who posit nature and commit evil: they claim that all things are natural, indulge their desires to create evil, and in the end return to nature. This turns one's back on desirelessness and indulges desires, going against the subtle to consort with the coarse. Just as Zhuang Zhou denounced benevolence and righteousness, saying that although they guard against petty thieves, he did not consider that great thieves would hold up benevolence and righteousness to plot against their states. Originally, nature was used to quell desires, yet they hold up nature to do evil; the meaning here can be understood.
