二諦義 2.72

2.72

問：俗諦中有四句，真諦中亦有四句不？解云：真諦但有兩句，一者是真是諦、二者是真非諦。是真是諦，此可知，真必是諦也。言是真非諦者，隨真說故是真，非情謂之實故非諦，如前隨俗諦說非俗諦，今亦爾也。

Question: There are four propositions in conventional truth; are there also four propositions in ultimate truth? Explanation: In ultimate truth there are only two propositions: first, it is both ultimate and a truth; second, it is ultimate and not a truth. That it is both ultimate and a truth can be known, for the ultimate must be a truth. As for saying 'it is ultimate and not a truth', because it is spoken in accordance with the ultimate it is ultimate, but because it is not the real of sentimental conception it is not a truth—just as previously what was spoken in accordance with conventional truth was not conventional truth, so it is here as well.
