大般涅槃經疏 15.9

15.9

「善男子云何」下，第四廣明道諦。文為二：初明道諦、次會通。初為三：一章門、二解釋、三結。釋中，先譬、次合。初譬中言因燈者，即譬八道。然燈照物，物即常無常等雖異，終是一道隨緣異說。次合譬中云陀羅驃者，河西云：是真實諦。求那，是莊嚴瓔珞功德等。舊云主諦、依諦。非陀羅即非真，非求那即非俗。

From 'Good son, how' onward is the fourth, extensively clarifying the truth of the path. The text is twofold: first, clarifying the truth of the path; second, reconciling and harmonizing. The first part is threefold: 1. the heading; 2. explanation; 3. conclusion. Within the explanation, first is the analogy, next the application. In the first, the analogy, the mention of 'due to a lamp' is an analogy for the eightfold path. Now, a lamp illuminates objects; although objects differ as permanent, impermanent, and so forth, it is ultimately a single path differently explained according to conditions. Next, in applying the analogy, the mention of *dravya* (tuoluopiao): Héxī says it is the real truth (paramārtha-satya). *Guṇa* (qiunā) is ornamentation, necklaces, meritorious qualities, and the like. An old commentary says: primary truth and secondary truth. Not being *dravya* means not being the ultimate; not being *guṇa* means not being the conventional.
