大般涅槃經義記 2.17

2.17

In the second major section, which presents defilements to make the request, the text is divided into five parts: the first two show that their own ignorance has not yet been dispelled and request the Buddha to remain and sever it; the next two show that their own four entrenchments have not yet perished and request the Buddha to remain and sever them; the last one shows that their own inverted conceptions have not yet been eliminated and requests the Buddha to remain and sever them. Why do the bhikṣus cite these to request their severance? Because earlier the Buddha, in separately overturning the cause, stated: "After the Ten Powers have passed into extinction, you will be covered by ignorance"; therefore, they cite ignorance to request the Buddha to teach its severance. Because earlier the Buddha exhorted the crushing of the defilements, they cite the four entrenchments to request the Buddha to remain and sever them. Because earlier the Buddha said: "My Dharma can serve as a good medicine for illness", they cite inverted conceptions to request the Buddha to remain and sever them.
