四分律行事鈔資持記 2.907

2.907

不犯有九。前五皆據師友匠成，語雖麁惡，內無瞋怒，故在開位，如注顯之。疏云：片涉譏嫌，即是正墮。然瞋心難狀，非智莫曉。彌須審悉，不可自欺；初言相利，即泛爾同學，異下親友。四云教授，謂直示時事，異上說法說律也。餘四即約掉散遺失。注犯吉者，以乖儀故。失口謂心知語失，異下忘誤。

There are nine instances of non-violation. The first five all rely on masters and friends training and shaping [the student]; although the words are coarse and harsh, internally there is no anger, and therefore they fall under the allowed position, as shown in the note. The commentary says: slightly touching upon criticism or disdain directly constitutes a pāyattika. However, the angry mind is difficult to discern, and none but the wise can know it. One must be especially discerning and not deceive oneself. The first mentions "mutual benefit", which refers to casual fellow students, distinct from close friends below. The fourth says "instruction", which means directly indicating practical matters, distinct from explaining the Dharma and explaining the vinaya above. The remaining four relate to restlessness and slips. The note stating it violates a duṣkṛta is because it contravenes deportment. A slip of the tongue means that the mind realizes the verbal error, distinct from forgetting and mistakes below.
