大般涅槃經義記 9.164

9.164

自下第三約人舉類。於中，初約五種惡人以舉其類，「是故我先告舍利」下約就利鈍二人舉類。前中有三：一舉昔言，明五眾生不應還為說五種法。問曰：經說慳貪眾生教行布施，乃至癡者教修智慧，今以何故不信人前不讚正信，乃至癡前不讚智慧？釋言：隨人不同故爾。若人內有出世道機、厭患己過，則須當病為說對治，慳為說施，乃至癡者為說智慧。若無道機、不厭己過，則須將護，不信人前不讚正信，乃至癡前不讚智慧。二「何以故」下，釋前不得為說所以，若說不名知根憐生。三何以下釋前不名知根憐生。是人聞說起惡受苦，是故不名憐生知根。

From here below is the third [section], adducing categories with reference to persons. Therein, it first adduces categories with reference to five kinds of bad people; "Therefore I previously told Śāri[putra]..." and below adduces categories with reference to the two kinds of persons, sharp and dull. Within the former there are three parts: First, citing past statements to explain that for five kinds of sentient beings one should not in turn speak of five kinds of dharmas. Question: The sūtra states that one should teach stingy sentient beings to practice giving, and up to teaching foolish ones to cultivate wisdom; why is it that now, in front of faithless people, one does not praise correct faith, and up to not praising wisdom in front of foolish ones? Explanation: It is because it varies according to the person. If a person internally possesses the capacity for the supramundane path and is disgusted with their own faults, then one must speak the antidote to counter the illness—speaking of giving for stinginess, and up to speaking of wisdom for the foolish. If they lack the capacity for the path and are not disgusted with their own faults, then one must protect them, not praising correct faith in front of faithless people, and up to not praising wisdom in front of the foolish. Second, "Why?" and below explains the reason why one must not speak [these things] as mentioned above: if one speaks them, it is not called knowing faculties and pitying sentient beings. Third, "Why?" and below explains the preceding [point of] not being called pitying sentient beings and knowing faculties: when these people hear the teaching they give rise to unwholesomeness and undergo suffering, and therefore it is not called pitying sentient beings and knowing faculties.
