大般涅槃經疏 24.6

24.6

「復次眾生起見」下，是第三不斷不常明中道，又三：一唱章門、二釋、三結。初章門中，明凡夫菩薩二乘，前後舉非、中間明是。次「佛性雖常」下，即釋也。又三：先釋凡夫，為無明所覆故起斷常。次「又未能度」下，釋二乘，只為兔馬不盡河底。二乘智偏沈空取證，不見佛性無常無斷。「是觀十二因緣」下，第三釋菩薩章。十二因緣即是觀境，菩薩觀境生智，合取境智皆名中道。

From "Furthermore, sentient beings give rise to views" below is the third, clarifying the middle way through neither annihilation nor permanence; it also has three: first, proclaiming the chapter heading; second, explaining it; third, concluding it. In the opening chapter heading, it clarifies ordinary beings, bodhisattvas, and the two vehicles: beforehand and afterward it presents the incorrect, and in the middle clarifies the correct. Next, from "Although the buddhadhātu is permanent" below is the explanation. It also has three: first, it explains ordinary beings, who, being veiled by ignorance, give rise to [views of] annihilation and permanence. Next, from "Moreover, having not yet crossed" below, it explains the two vehicles: simply because the hare and the horse do not reach the bottom of the river. The two vehicles' wisdom is biased, sinking into emptiness to realize attainment, failing to see that the buddhadhātu is neither impermanent nor annihilated. From "One who contemplates the twelve links of dependent origination" below is the third, explaining the section on bodhisattvas. The twelve links of dependent origination are the object of contemplation; the bodhisattva contemplates the object and generates wisdom; taking the object and wisdom together, both are called the middle way.
