Be not elated at any advantage (excellence), which belongs to another. If a horse when he is elated should say, I am beautiful, one might endure it. But when you are elated, and say, I have a beautiful horse, you must know that you are elated at having a good horse. What then is your own? The use of appearances. Consequently when in the use of appearances you are conformable to nature, then you will be elated, for then you will be elated at something good which is your own. As on a voyage when the vessel has reached a port, if you go out to get water, it is an amusement by the way to pick up a shell fish or some bulb, but your thoughts ought to be directed to the ship, and you ought to be constantly watching if the captain should call, and then you must throw away all those things, that you may not be bound and pitched into the ship like sheep: so in life also, if there be given to you instead of a little bulb and a shell a wife and child, there will be nothing to prevent (you from taking them). But if the captain should call, run to the ship, and leave all those things without regard to them. But if you are old, do not even go far from the ship, lest when you are called you make default. Seek not that the things which happen should happen as you wish; but wish the things which happen to be as they are, and you will have a tranquil flow of life.
