Isn't the negation on the wrong thing? {jItIwmo' jIvangbe'} reads like "my commitment to non-action is emotional".
I'd expect something like {jIvangtaHvIS jItIwbe'} or {jItIwbe'mo' jIvangtaH net SIghbe'}, where the {-be'} is attached to {tIw}.
It seems neither {tIw} nor {vang} should be negated in this case. What needs negating is the causation expressed by {-mo'}, but known grammar rules preclude a rover after a VS9 so it can't be negated that way, nor is there any known adverbial that can do it. The same could happen with {-meH} when purpose is what needs to be negated. Maybe something like: {muvangmoHbe' tIwmeH laHwIj} "My capacity for reacting emotionally does not me to act."
