首楞嚴義疏注經 8.453

8.453

此獨一根只犯一殺，又輕於前，入一百八獄。如意中邪思或不正見，未形身口。或口處殺人，身心無記。此等竝輕。言見見者，見，現音，只見之一根，不兼餘根，故云見見。

This is when a single faculty alone commits merely one act of killing, which is again lighter than the former; one enters the one hundred and eight hells. For example, when there is perverse thinking or wrong view in the mind that has not yet manifested in body and speech; or when speech kills someone while body and mind are ethically neutral. These are all light. Speaking of "one faculty of perception alone" (*jian jian*): *jian* is pronounced *xian*; it means the single faculty of perception manifest, not combining with other faculties, hence it says *jian jian*.
