Satipatthana Sutta: Third Foundation, Division Through Anger

Anger is often unconsciously encouraged because is clears away the doubting mind. "I know why I feel this way, and I am right," says anger. Spiritually we can only approach and understand anger from humility, the opposite direction of righteousness. Anger usually arises as a component of grief where something you cared about was blocked or diverted away from you. If we can see anger as grief, humility is more easily accessed.
