I dunno, I'm not prone to resentment. Anxiety, occasional anger, regret (for my own fails) - perhaps (and the practice helps a lot with these) but resentment - I can only speculate about how does it feel. I just know nobody but me myself, people's illusions (people themselves are perfect, their brains just are prone to misjudgment and unconscious behavior, as is mine although mine is already quite trained and less prone to these this way) and unfortunate consequences (which are nothing but a perfectly neutral manifestation of pure chaos) can be "guilty" in anything I would dislike. Resentment doesn't ever seem making any sense.
