金光明經文句記 1.145

1.145

二、「若緣」下，明中必融攝。佛或對機用於權智偏照二諦，既不攝中，故非遊於無量法性；今用實智照中諦理，中無不攝，故云若緣中道即三智一心等，是以中諦稱為無量。

Second, from "If taking as condition" below, clarifying that the middle must interfuse and assimilate. When the Buddha, facing capacities, employs provisional wisdom to illuminate the two truths in a biased way, since it does not assimilate the middle, it is not roaming in the immeasurable Dharma-nature. Now, employing real wisdom to illuminate the principle of the truth of the middle, the middle assimilates everything; therefore he says that if one takes the Middle Way as condition, it is precisely the three wisdoms in one mind and so forth; hence the truth of the middle is called immeasurable.
