Evenness of mind; that calm temper or firmness of mind which is not easily elated or depressed; patience; calmness; composure; as, to bear misfortunes with equanimity.
Even a happy life cannot be without a measure of darkness, and the word happy would lose its meaning if it were not balanced by sadness. It is far better take things as they come along with patience and equanimity. Carl Jung
Few people are capable of expressing with equanimity opinions which differ from the prejudices of their social environment. Most people are even incapable of forming such opinions. Albert Einstein
A son can bear with equanimity the loss of his father, but the loss of his inheritance may drive him to despair. Niccolo Machiavelli
