Serenity

CALMNESS of mind is one of the beautiful jewel of wisdom. It is the result of long and patient effort in self-control. It's presence is an indication of ripened experience, and of a more than ordinary knowledge of the laws and operations of thought.
The calm mas, having learned how to govern himself, knows hoe to adapt himself to others. The more tranquil a man becomes, the greater in his success, his influence, his power for good. The strong calm man is always loved and reversed.
