“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.”

“For it is in your power to retire into yourself whenever you choose.”

“Because your own strength is unequal to the task, do not assume that it is beyond the powers of man; but if anything is within the powers and province of man, believe that it is within your own compass also. Marcus Aurelius”

“Is your cucumber bitter? Throw it away. Are there briars in your path? Turn aside. That is enough. Do not go on and say, "Why were things of this sort ever brought into this world?" neither intolerable nor everlasting - if thou bearest in mind that it has its limits, and if thou addest nothing to it in imagination. Pain is either an evil to the body (then let the body say what it thinks of it!)-or to the soul. But it is in the power of the soul to maintain its own serenity and tranquility. . . .”

“You have power over your mind - not outside events. Realize this, and you will find strength.”

“If you are pained by external things, it is not they that disturb you, but your own judgement of them. And it is in your power to wipe out that judgement now.”

“Very little is needed to make a happy life; it is all within yourself in your way of thinking.”
