"Threefold is this gate of hell, destructive of the self — lust, anger, greed. Therefore one should abandon these three."
Modern explanation
In the middle of the day, return to this: Anger is not your enemy; obedience to anger is. The same fire can warm or burn.
Practical application
Before responding to the thing irritating you, draft your reply, wait ten minutes, then re-read it.
Reflection question
What boundary is this anger asking me to set, calmly?
