法華文句記 9.17

9.17

附事者，離十惱亂等事中下文亦觀空等，如引義中寂滅忍與畢竟空豈容深淺？但對事說得忍衣名，約理以說得空座名，故附事必依理，從理必經事，不應圓行事理條然，亦如二諦必真俗相即，各說一邊非無所詣，約行準說。

Regarding 'applying to phenomena': within the phenomenal matters such as leaving the ten disturbances, the text below also contemplates emptiness and so forth. Just as in the cited meaning, how could there be shallow or deep between the forbearance of quiescence and ultimate emptiness? It is merely that when spoken in relation to phenomena it receives the name of the robe of forbearance, while when spoken in terms of principle it receives the name of the seat of emptiness. Therefore, applying to phenomena must rely on principle, and proceeding from principle must pass through phenomena; in perfect practice, phenomena and principle should not be completely distinct. It is also just as the two truths must have the ultimate and conventional mutually identical: each speaking of one side does not mean they lack that to which they tend; they are explained in accordance with practice.
