The sinner sins against himself; the wrongdoer wrongs himself, becoming the worse by his own action.

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.

Your task is to stand straight; not to be held straight.

Things can never touch the soul, but stand inert outside it, so that disquiet can arise only from fancies within.

Everything that happens, happens as it should.

Take away the complaint, 'I have been harmed,' and the harm is taken away.

It doesn't hurt me unless I interpret its happening as harmful to me. I can choose not to.
