大般涅槃經疏 19.16

19.16

「爾時佛告」下，第三如來稱歎，又為四：一王歎疑、二佛為決定、三持一切問、四佛答。初言疑者，疑於佛智能除不能除，疑己罪可除不可除。次「我今」下，佛作決定，以能除智除可除罪。三「爾時」下，持一切問。佛說一切無定，云何為王而作定說？四「佛言」下答。王自謂可除不可除？我為其除，除其不定為定。

From "At that time the Buddha addressed" onwards is the third part: the Tathāgata's praise and commendation, which also has four parts: first, the king expresses his doubt; second, the Buddha resolves it definitively; third, bringing forward all things to question; fourth, the Buddha answers. First, speaking of doubt means doubting whether the Buddha's wisdom can eliminate it or cannot eliminate it, and doubting whether his own crime can be eliminated or cannot be eliminated. Next, from "I now" onwards, the Buddha makes a definitive resolution, using the wisdom that can eliminate it to eliminate the crime that can be eliminated. Third, from "At that time" onwards, he brings forward all things to question: The Buddha stated that all things are indeterminate; why then did he make a determinate exposition for the king? Fourth, from "The Buddha said" onwards is the answer: Did the king himself think it could be eliminated or could not be eliminated? I eliminated it for him, eliminating his indeterminacy to make it determinate.
