Reference request: blame as the source of anger? I am looking for a textual reference. I cannot recall the exact details but I will try my best; if anyone knows what I am referring to and can point me to the text, it would be much appreciated.

The basic idea in the passage was roughly, I believe, that if one doesn't have anyone who can tell them what to do or not do...doesn't have a person who can punish them, then they won't become angry. I believe I read this in the Visuddhimagga but I'm not sure. Any help is appreciated!
He abused me, he beat me, he defeated me, he robbed me of my property. Whosoever harbor such thoughts will never be able to still their enmity.
Never indeed is hatred stilled by hatred; it will only be stilled by non-hatred — this is an eternal law.
— Dhp., vv. 4-5

The bolded text implies they blame the other for one's plight.
