Because your own strength is unequal to a task, do not assume it is beyond the powers of man.

Bear in mind that the measure of a man is the worth of the things he cares about.

The true worth of a man is to be measured by the objects he pursues.

How easy it is to repel and release every impression which is troublesome and immediately to be tranquil.

It is the duty of men to love even those who injure them.

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. . . .

All things change, and you yourself are constantly wasting away. So also is the universe.
