Courage
Courage is not valour. Valour is a function of the heart (not the physiological heart; but our ‘feeling core’). Courage, the function of a heart that is mature and also in the habit of obeying a wise will.
When we display valour, and that comes from a heart so trained, there is courage. Courage hence manifests as grace under pressure. On its own, valour can be mere audacity and can turn out to be churlish.
Anger can be directly proportional to valour, but courage is often inversely proportional to anger.
