瑜伽論記 17.101

17.101

下別解釋中，景云：言設有染心不起欲樂，而得究竟，非是圓滿者，既無欲樂，云何究竟成根本業？解云：如人殺時運手動足誤殺蟲，雖行殺非本意樂，不成業道。

In the detailed explanation below, Jing says: Regarding the statement, 'suppose there is a defiled mind, but one does not give rise to desire and pleasure, yet culmination is reached, this is not complete': since there is no desire and pleasure, how could culmination accomplish a fundamental karma? It is explained: For example, when a person kills, moving hands and feet, they kill an insect by mistake; although an act of killing is performed, it was not their original intention or desire, so it does not constitute a course of karma.
