法華義疏 10.21

10.21

次就三諦釋此文者，住忍辱地等謂世諦觀，於法無所行而觀實相謂真諦觀，亦不行不分別謂非真非俗中道觀。不行者不行真諦也，不分別者不分別世諦事也，故名非真非俗中道觀。此三諦是因緣義，以不二言二，二名二諦，二不二為中道也。

Next, explaining this passage in terms of the three truths: abiding in the ground of forbearance and so forth refers to the contemplation of worldly truth; having nothing to practice with respect to dharmas and contemplating the real mark refers to the contemplation of ultimate truth; also not practicing and not discriminating refers to the contemplation of the Middle Way, which is neither ultimate nor worldly. 'Not practicing' means not practicing ultimate truth; 'not discriminating' means not discriminating the affairs of worldly truth; hence it is called the contemplation of the Middle Way, which is neither ultimate nor worldly. These three truths are the meaning of dependent arising: speaking of two based on the non-dual, the two are called the two truths; the non-duality of the two is the Middle Way.
