[1020] Therein, which are the nine grounds for resentment (āghātavatthu)?
Resentment (āghāta) arises [thinking]: "He has done me harm (anattha)." Resentment arises [thinking]: "He is doing me harm." Resentment arises [thinking]: "He will do me harm." Resentment arises [thinking]: "He has done harm, he is doing harm, he will do harm to one who is dear and pleasing to me." Resentment arises [thinking]: "He has done good (attha), he is doing good, he will do good to one who is not dear and not pleasing to me." These are the nine grounds for resentment.
