大般涅槃經義記 5.192

5.192

「有為之法凡有二」下破向中間五句計常，於中初先分法為二，後就此二破其所計。

From 'Conditioned dharmas generally are of two kinds' below, it refutes the previous intermediate five statements conceptualising permanence, within which it first divides dharmas into two, and afterwards refutes what they conceptualise based on these two.
