成唯識論述記 4.59

4.59

述曰：此第三義，二法俱是還滅品類之所攝故。謂此意說，非唯道是還，涅槃是滅，道為能還，涅槃所還，故涅槃亦是還品類攝。滅是滅體，道亦順彼斷滅染法，以能順滅，故亦說是滅品類攝。道與涅槃俱可言還，俱可言滅，故言俱是還滅品攝。是彼品攝，非是彼體。何以得知此中雙說？

[The Commentary states:] This is the third view: because both factors are subsumed under the category of cessation. The intention here is to say that not only is the path return and nirvāṇa cessation, but the path is that which can return, and nirvāṇa is that which is returned to, hence nirvāṇa is also subsumed under the category of return. Cessation is the substance of cessation, and the path also conforms to it in severing defiled factors; because it can conform to cessation, it is also said to be subsumed under the category of cessation. Both the path and nirvāṇa may be called return, and both may be called cessation; hence it says both are subsumed under the category of return and cessation. They are subsumed under that category, but are not its substance. How is it known that both are spoken of here?
