法華文句記 6.58

6.58

秖以無燒名之為出，然則法應並皆無燒，應本同物從物云燒，從理則法應無壞，從事則物燒佛出。今說俱燒意在同出，故云若不等也。有云：感應俱時。今謂但得俱出之理，而失俱燒之義，故以俱燒要令同出。

It is simply by virtue of having no burning that it is called "coming out." However, both dharma and response are entirely without burning. The response body is fundamentally the same as beings, so in accordance with beings it is said to burn; in terms of principle, dharma and response are without destruction; in terms of phenomena, beings burn and the Buddha comes out. Now speaking of burning together, the intention lies in coming out together; hence it says "if not in time," and so forth. Some say: stimulus and response are simultaneous. We now say that this only grasps the principle of coming out together, but loses the meaning of burning together; therefore, by means of burning together, he requires that they come out together.
