淨名玄論 6.30

6.30

他但以空為真、有為俗，更無異說也。今有三轉：一以空有為俗、以有空為真。二以空有皆俗、非空有為真。三以空有為二、不空有為不二，二不二並俗、非二非不二為真。如此三轉二諦，皆是教門耳。至道竟不曾三，故云是法不可示。立此三重，凡有五義，《法華玄》中已說。

Others merely take emptiness as the real and existence as the conventional, having no other explanation. Here there are three transitions: First, taking emptiness and existence as conventional, and existence-emptiness as real. Second, taking emptiness and existence both as conventional, and neither-emptiness-nor-existence as real. Third, taking emptiness and existence as duality, and non-emptiness-and-existence as nonduality; duality and nonduality are both conventional, and neither duality nor nonduality is real. Such three transitions of the two truths are all merely gates of teaching. The ultimate Way has never been threefold; hence it is said, 'This Dharma cannot be shown.' Establishing these three levels has five meanings in all, which have already been explained in the Fahua xuan[lun].
