The philosopher's lecture room is a 'hospital': you ought not to walk out of it in a state of pleasure, but in pain; for you are not in good conditio… - Epictetus

When you see a person weeping in sorrow either when a. child goes abroad or when he is dead, or when the man has lost his property, take care that the appearance do not hurry you away with it, as if he were suffering in external things. But straightway make a distinction in your own mind, and be in readiness to say, it is not that which has happened that afflicts this man, for it does not afflict another, but it is the opinion about this thing which afflicts the man. So far as words then do not be unwilling to show him sympathy, and even if it happens so, to lament with him. But take care that you do not. lament internally also.

The Iliad consists of nothing more than impressions and the use of impressions. An impression prompted Paris to carry off the wife of Menelaus, and an impression prompted Helen to go with him. If an impression, then, had prompted Menelaus to feel that it was a gain to be deprived of such a wife, what would have come about? Not only the Iliad would have been lost, but the Odyssey too!

When you are feeling upset, angry, or sad,” Epictetus said, “don’t blame another for your state of mind. Your condition is the result of your own opinions and interpretations.” When anyone provokes you, remember that it is actually your own opinion provoking you. It is not the person who insults or attacks you who torments your mind, but the view you take of these things. Do not be fooled by how things first appear. With time and greater perspective, you can regain inner peace.
