四分律刪繁補闕行事鈔 2.415

2.415

Among them, within the primary [propositions of] not knowing the matter, there may be no offense, which means that there was no [guilty] mind from beginning to end, such as accidentally killing someone, except for the precepts on unchastity and alcohol. If in the midst [of the act] one's perception shifts, doubting the matter or not knowing the matter, because of the divergence of mind, it is a preliminary expedient; if it does not diverge, the primary [offense] is established. Or one might not carry out the intended action. Among these latter nine propositions, the three propositions of knowing the matter constitute the superior-grade performance transgression. The three propositions of doubt constitute the middling grade. The three propositions of not knowing the matter constitute the inferior grade, or are without offense. By applying this analogously to the rule, it can be understood.
