What more dost thou want when thou hast done a man a service? Art thou not content that thou hast done something conformable to thy nature, and dost thou seek to be paid for it? Just as if the eye demanded a recompense for seeing, or the feet for walking. As a horse when he has run, a dog when he has traced the game, a bee when it has made the honey, so a man, when he has done a good act, does not call out for others to come and see, but goes on to another act, as a vine goes on to produce again the grapes in season.
Accustom thyself to attend carefully to what is said by another, and as much as it is possible, be in the speaker's mind.
Some things are hurrying into existence, and others are hurrying out of it; and of that which is coming into existence, part is already extinguished. Motions and changes are continually renewing the world, just as the uninterrupted course of time is always renewing the infinite duration of ages.
Understand that every man is worth just so much as the things are worth about which he busies himself.
Wickedness does no harm at all to the universe—it is only harmful to him who has it in his power to be released from it.
Nothing is more wretched than a man who traverses everything in a round, and pries into the things beneath the earth, as the poet says, and seeks by conjecture what is in the minds of his neighbors, without perceiving that it is sufficient to attend to the deity within him, and to reverence it sincerely.
The prayers of Marcus Aurelius to the gods are for one thing only—that their will be done. All else is vain, all else is rebellion against the universe itself. Our form of worship should be like this: Everything harmonizes with me which is harmonious to thee, O Universe. Nothing for me is too early nor too late, which is in due time for thee. Everything is fruit to me which thy seasons bring, O Nature: from thee are all things, in thee are all things, to thee all things return.
In the morning when thou risest unwillingly, let this thought be present—I am rising to the work of a human being. Why, then, am I dissatisfied if I am going to do the things for which I exist, and for which I was brought into the world? Or have I been made for this, to lie in the bedclothes and keep myself warm? But this is more pleasant. Dost thou exist, then, to take thy pleasure, and not for action or exertion? Dost thou not see the little plants, the little birds, the ants, the spiders, the bees, working together to put in order their several parts of the universe? And art thou unwilling to do the work of a human being, and dost thou not make haste to do that which is according to thy nature?
Judge every word and deed which are according to Nature to be fit for thee, and be not diverted by the blame which follows.... But if a thing is good to be done or said, do not consider it unworthy of thee.
Since it is possible that thou mayest depart from life this very moment, regulate every act and thought accordingly.... Death certainly, and life, honor and dishonor, pain and pleasure, all these things equally happen to good men and bad, being things which make us neither better nor worse. Therefore they are neither good nor evil.
