When you have been compelled by circumstances to be disturbed in any manner, quickly return to yourself, and do not continue out of tune longer than the compulsion lasts. You will have increasing control over your own harmony by continually returning to it.

Because a thing is difficult for you, do not therefore suppose it to be beyond mortal power. On the contrary, if anything is possible and proper for man to do, assume that it must fall within your own capacity.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.

To the wise, life is a problem; to the fool, a solution.

Whenever you are about to find fault with someone, ask yourself the following question: What fault of mine most nearly resembles the one I am about to criticize?

Remember that to change your mind and follow him who sets you right is to be none the less free than you were before.
