1. Say this to yourself in the morning: Today I shall have to do with meddlers, with the ungrateful, with the insolent, with the crafty, with the envious and the selfish. All these vices have beset them, because they know not what is good and what is evil. But I have considered the nature of the good, and found it beautiful: I have beheld the nature of the bad, and found it ugly. I also understand the nature of the evil-doer, and know that he is my brother, not because he shares with me the same blood or the same seed, but because he is a partaker of the same mind and of the same portion of immortality. I therefore cannot be hurt by any of these, since none of them can involve me in any baseness. I cannot be angry with my brother, or sever myself from him, for we are made by nature for mutual assistance, like the feet, the hands, the eyelids, the upper and lower rows of teeth. It is against nature for men to oppose each other; and what else is anger and aversion? 2. All that I am is either flesh, breath, or the ruling part. Cast your books from you; distract yourself no more; for you have not the right to do so. Like one at the point of death despise this flesh, this corruptible bone and blood, this network texture of nerves, veins, and arteries. Consider, too, what breath is--mere air, and that always changing, expelled and inhaled again every moment. The third is the ruling part. As to this, take heed, now that you are old, that it remain no longer in servitude; that it be no more dragged hither and thither like a puppet by every selfish impulse. Repine no more at what fate now sends, nor dread what may befall you hereafter. 3. Whatever the Gods ordain is full of wise forethought. The workings of chance are not apart from nature, and not without connexion and intertexture with the designs of Providence. Providence is the source of all things; and, besides, there is necessity, and the utility of the Universe, of which you are a part. For, to every part of a being, that is good which springs from the nature of the whole and tends to its preservation. Now, the order of Nature is preserved in the changes of elements, just as it is in the changes of things that are compound. Let this suffice you, and be your creed unchangeable. Put from you the thirst of books, that you may not die murmuring, but meekly, and with true and heartfelt gratitude to the Gods. 4. Think of your long procrastination, and of the many opportunities given you by the Gods, but left unused. Surely it is high time to understand the Universe of which you are a part, and the Ruler of that Universe, of whom you are an emanation; that a limit is set to your days, which, if you use them not for your enlightenment, will depart, as you yourself will, and return no more.
