法華玄論 4.179

4.179

次就此經後段明一種二智者，此經後段辨本迹常無常二智。識本是無生滅無始終為實智，識始終生滅等用謂權智。故初段具三種二智，第二段常無常二智，故此經具四種二智也。晚見論分明廣說法身是常、化身無常，則四種二智便成，五時權實皆壞矣。

Next, clarifying the one kind of dual wisdom with respect to the latter section of this sūtra: The latter section of this sūtra distinguishes the two wisdoms of the fundamental and the trace, the permanent and the impermanent. Recognizing that the fundamental is without arising or cessation, without beginning or end, is real wisdom; recognizing active functions such as beginning and end, arising and cessation, is called provisional wisdom. Therefore the first section is complete in three kinds of dual wisdom, and the second section has the two wisdoms of the permanent and the impermanent; hence this sūtra is complete in four kinds of dual wisdom. Later, seeing the treatise clearly and extensively explaining that the dharmakāya is permanent and the nirmāṇakāya is impermanent, the four kinds of dual wisdom are then established, and the provisional and real of the five periods are completely dismantled.
