大乘百法明門論開宗義決 1.6

1.6

具明真俗雙顯有空等者。於五法中。前之四法具明俗諦。第五無為具明真諦。前五種法即是顯有。後二無我即顯其空。既此真俗有之與空體不相離。即此真俗非有非空。不著二邊得中道也。

Regarding "Fully explaining the ultimate and conventional, mutually revealing existence and emptiness, etc.": Among the five categories of dharmas, the first four dharmas fully explain the saṃvṛti-satya; the fifth, the asaṃskṛta, fully explains the paramārtha-satya. The first five kinds of dharmas reveal existence; the latter twofold selflessness reveals their emptiness. Since the paramārtha-saṃvṛti, existence and emptiness, are not separate in substance, these paramārtha-saṃvṛti are neither existent nor empty. By not clinging to the two extremes, one attains the madhyamā-pratipad.
