If I and my two children cannot move the gods, the gods must have their reasons.

Live not as though there were a thousand years ahead of you. Fate is at your elbow; make yourself good while life and power are still yours.

Nature which governs the whole will soon change all things which you see, and out of their substance will make other things and again other things... in order that the world may be ever new.

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.

Keep in mind how fast things pass by and are gone - those that are now, and those to come. Existence flows past us like a river; the "what" is in constant flux, the "why" has a thousand variations. Nothing is stable, not even what's right here. The infinity of past and future gapes before us - a chasm whose depths we cannot see.

A man does not sin by commission only, but often by omission.

Whatever may happen to you was prepared for you from all eternity; and the implication of causes was from eternity spinning the thread of your being.
