Lama Ole’s answer:
If it helps you avoid anger, then it is okay to have a feeling of arrogance or any other substitute feeling. You can have this until you get tired of it—then it will also leave.
Treat anger like a poison: You simply have to split it into less dangerous components and then break it down further. In the end, you can spread it on the ground as fertilizer.
Almost any means is allowed to avoid anger. I also recommend you to think, “I only have to spend ten minutes with him, but he has to be with himself twenty-four hours a day, seven days a week.” This is also slightly arrogant, because you put yourself above someone else. But if it keeps you away from an outburst of anger, then it has been useful as well.
In the end one merely watches and thinks, “Why does he do that?” One doesn’t have any anger anymore and can’t understand where it went.
