Dig within. There lies the wellspring of good.

"Sweep me up and send me where you please." For there I will retain my spirit, tranquil and content, as long as it can feel and act in harmony with its own nature. Is a change of place enough reason for my soul to become unhappy and worn, for me to become depressed, humbled, cowering, and afraid? Can you discover any reasons for this?

He who does wrong does wrong against himself. He who acts unjustly acts unjustly to himself, because he makes himself bad.

Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.

In reading and writing, you cannot lay down rules until you have learnt to obey them. Much more so in life.

This is enough. Do not add, And why were such things made in the world?

Nothing that goes on in anyone else's mind can harm you.
