Just as anger is a
sign of an unstable emotion,
calmness is a
sign of stable reason.
Many people think that to be patient in bearing loss is a sign of weakness. I think this is a mistake. It is anger that is a sign of weakness, whereas patience is a sign of strength. For example, a person arguing a point based on sound reasoning remains confident and may even smile while proving his case.
On the other hand, if his reasons are unsound and he is about to lose face, he gets angry, loses control, and starts talking nonsense. People rarely get angry if they are confident in what they are doing. Anger comes more easily in moments of confusion.
