（二）（瞋根）其次瞋根（的不善心）有二种：（30）忧俱瞋恚相应无行，及（31）（忧俱瞋恚相应）有行。当知它们是在于行杀生等的时候而转起的锐利和迟钝的心。

Ñ(XIV,92): II. (b) That rooted in hate is of two kinds: (30)-(31) being accompanied-by-grief and associated-with-resentment, it is either prompted or unprompted. It should be understood to occur at the times when [consciousness] is either keen [if unprompted] or sluggish [if prompted] in the killing of living things, and so on.
