Men are disturbed not by the things which happen, but by the opinions about the things: for example, death is nothing terrible, for if it were, it would have seemed so to Socrates; for the opinion about death, that it is terrible, is the terrible thing. When then, we are impeded or disturbed or grieved, let us never blame others, but ourselves, that is, our opinions. It is the act of an ill-instructed man to blame others for his own bad condition; it is the act of one who has begun to be instructed, to lay the blame on himself; and of one whose instruction is completed, neither to blame another, nor himself.
When you are going to take in hand any act, remind yourself what kind of an act it is. If you are going to bathe, place before yourself what happens in the bath: some splashing the water, others pushing against one another, others abusing one another, and some stealing: and thus with more safety you will undertake the matter, if you say to yourself, I now intend to bathe, and to maintain my will in a manner conformable to nature. And so you will do in every act: for thus if any hindrance to bathing shall happen, let this thought be ready; it was not this only that I intended, but I intended also to maintain my will in a way conformable to nature; but I shall not maintain it so, if I am vexed at what happens.
In everything which pleases the soul, or supplies a want, or is loved, remember to add this to the (description, notion): What is the nature of each thing, beginning from the smallest? If you love an earthen vessel, say it is an earthen vessel which you love; for when it has been broken, you will not be disturbed. If you are kissing your child or wife, say that it is a human being whom you are kissing, for when the wife or child dies, you will not be disturbed.
Remember that desire contains in it the profession (hope) of obtaining that which you desire; and the profession (hope) in aversion (turning from a thing) is that you will not fall into that which you attempt to avoid: and he who fails in his desire is unfortunate; and he who falls into that which he would avoid, is unhappy. If then you attempt to avoid only the things contrary to nature which are within your power, you will not be involved in any of the things which you would avoid. But if you attempt to avoid disease or death or poverty, you will be unhappy.
Take away, then, aversion from all things which are not in our power, and transfer it to the things contrary to nature which are in our power. But destroy desire completely for the present. For if you desire anything which is not in our power, you must be unfortunate: but of the things in our power, and which it would be good to desire, nothing yet is before you. But employ only the power of moving toward an object and retiring from it; and these powers indeed only slightly and with exceptions and with remission.
