法華玄論 5.17

5.17

答：亦有四句，一者以三顯一、二以一顯三、三者以三顯三、四以一顯一。初兩句如前。以三顯三、以一顯一者，言昔三異今一，此三在一外；今一異昔三，此一在三外，故一非三一、三非一三。如此一三皆是執見，今破此病故云於一佛乘分別說三，故三是一三；汝等所行是菩薩道，故一是三一。以三是一三，三豈異一？一是三一，一豈異三？故名三一因緣之義。以今因緣三一顯自性三一，亦以自性三一顯因緣三一，故云以三顯三、以一顯一。

Answer: There are also four propositions: first, using the three to reveal the one; second, using the one to reveal the three; third, using the three to reveal the three; fourth, using the one to reveal the one. The first two propositions are as stated before. As for using the three to reveal the three and using the one to reveal the one: saying that the past three differed from the present one, these three were outside the one; the present one differed from the past three, this one was outside the three; therefore, the one was not the one of the three, and the three were not the three of the one. Such 'one' and 'three' were entirely attachments to views. Now, to break this defect, it is said that 'Within the one Buddha vehicle, he discriminates and teaches the three'; therefore, the three are the three of the one. 'That which you practice is the bodhisattva path'; therefore, the one is the one of the three. Since the three are the three of the one, how could the three differ from the one? Since the one is the one of the three, how could the one differ from the three? Hence this is named the meaning of the dependent arising of three and one. Using the present dependently arisen three and one to reveal the three and one of self-nature, and also using the three and one of self-nature to reveal the dependently arisen three and one, is therefore called using the three to reveal the three and using the one to reveal the one.
