“The more tranquil a man becomes, the greater is his success, his influence, his power for good. Calmness of mind is one of the beautiful jewels of wisdom.”

“Calmness of mind is one of the beautiful jewels of wisdom. It is the result of long and patient effort in self-control. Its presence is an indication of ripened experience, and of a more than ordinary knowledge of the laws and operations of thought.”

“The mind becomes much more beautiful, when man could see his own weaknesses.”

“In a pre-scientific society the best the common man can do is pin his faith on a leader and give him his support, trusting in his benevolence against the misuse of the delegated power and in his wisdom to govern justly and make war successfully.”

“A human being in perfection ought always to preserve a calm and peaceful mind and never to allow passion or a transitory desire to disturb his tranquility.”

“A man of over thirty might be held to be at the height of his powers, but not necessarily of his wisdom.”
