As a man, casting off worn out garments taketh new ones, so the dweller in the body, entereth into ones that are new.

What else can I do, a lame old man, but sing hymns to God? If I were a nightingale, I would do the nightingale's part; if I were a swan, I would do as a swan. But now I am a rational creature, and I ought to praise God. This is my work. I do it, nor will I desert my post, so long as I am allowed to keep it. And I ask you to join me in this same song.

The wise realize that some things are within their control, and most things are not. They learn early on to distinguish between what they can and can't regulate.

I must die. I must be imprisoned. I must suffer exile. But must I die groaning? Must I whine as well? Can anyone hinder me from going into exile with a smile? The master threatens to chain me: what say you? Chain me? My leg you will chain--yes, but not my will--no, not even Zeus can conquer that.

There is but one way to tranquility of mind and happiness, and that is to account no external things thine own, but to commit all to God.

Don't just say you have read books. Show that through them you have learned to think better, to be a more discriminating and reflective person. Books are the training weights of the mind. They are very helpful, but it would be a bad mistake to suppose that one has made progress simply by having internalized their contents." Translation by Sharon Lebell
