“By a tranquil mind I mean nothing else than a mind well ordered.”

“Viewed from an evolutionary perspective, mind is not the cause of the order in nature; mind is an example of the order in nature - something to be explained rather than the explanation for everything else.”

“[P]eace of soul implies tranquillity of order, with material things ordered to the body, the body to the soul, the personality to neighbor and to God. Peace of mind is subjective tranquillity — a narrower thing. It requires great moral effort to attain peace of soul, but even those who are indifferent to right and wrong sometimes achieve peace of mind”

“It is in your power to withdraw yourself whenever you desire. Perfect tranquility within consists in the good ordering of the mind, the realm of your own.”

“A happy life consists in tranquility of mind.”

“I mean, I have the feeling that something in my mind is poisoning everything else.”

“Nothing contributes so much to tranquillize the mind as a steady purpose- a point on which the soul can focus its intellectual eye”

“When one cultivates strong concentration by means of tranquility or insight meditation, the mind is no longer distracted by thoughts and other hindrances. Such pure concentration, continuously focused on an object for either tranquility or insight, is considered mental purification. A mind associated with such concentration is also purified of hindrances due to the power of the concentration.”

“Trust Christ! and a great benediction of tranquil repose comes down upon the calm mind and the tranquil heart.”

“The biggest battle than all the world wars put together is when the mind wants something while the body craves for something else as well.”
