大般涅槃經疏 20.10

20.10

四釋慧心正直無曲，亦三：標、釋、結。初標。前明內證三智、外離諸疑，未知何智？今標正直之智，非是二邊，所以雙舉正直、邪曲兩章。次釋出，既識二邊，正直自顯。菩薩修聖行時已能除凡夫二乘邪曲，當知五行是修；曲見既除，所見則正，當知十德是證明矣。釋聲聞曲見，如文。三「修行如是」下，結，可解。

Fourth, explaining "the mind of wisdom is upright and without deviousness" also has three parts: the presentation, the explanation, and the conclusion. First is the presentation. The preceding clarified the three wisdoms of internal realization and the external departure from all doubts, but it was not yet known which wisdom this is. Now it presents the upright wisdom that is free from the two extremes; therefore, it raises both headings: upright and devious. Next, in explaining them, once the two extremes are recognized, the upright reveals itself. When the bodhisattva cultivated the noble practices, he was already able to eliminate the deviousness of ordinary people and the two vehicles, from which we should know that the five practices are cultivation; once devious views are eliminated, what is seen is upright, from which we should know that the ten virtues are clearly realization. The explanation of the devious views of the śrāvakas is as in the text. Third, from "practicing like this" downward is the conclusion, which is easy to understand.
