大般涅槃經義記 7.42

7.42

後四難中，第一難上生生之義、第二難上生不生義、第三難上不生生義、第四難上不生不生義。此將生相對法為難，以何義故不依前次？良以初二自、他相對，後二幼時有、無相對，隨此便故不依前次。

Among the latter four objections: the first objects to the aforementioned meaning of "arising when arisen"; the second objects to the aforementioned meaning of "not arising when arisen"; the third objects to the aforementioned meaning of "arising when not [yet] arisen"; the fourth objects to the aforementioned meaning of "not arising when not [yet] arisen." This poses objections by juxtaposing the mark of arising with the dharmas. For what reason does it not follow the previous order? Truly, because the first two contrast self and other, while the latter two contrast the presence and absence of arising at the nascent stage, it follows this convenience and does not adhere to the previous order.
