Epictetus 3.22.30-34
It is not in royalty. Otherwise Nero would have been a happy man, and Sardanapalus. Nay, even Agamemnon was not a happy man, though a much finer fellow than Sardanapalus or Nero; but while the rest are snoring what is he doing? "Many a hair did he pluck, by the roots, from his forehead." And what are his own words? "Thus do I wander," he says, and "To and fro am I tossed, and my heart is Leaping forth from my bosom." Poor man, what about you is in a bad state? Your possessions? No, it is not; rather you "are possessed of much gold and of much bronze." Your body? No, it is not. What, then, is wrong with you? Why, this: You have neglected and ruined whatever that is within you by which we desire, avoid, choose, and refuse. How neglected? It remains ignorant of the true nature of the good, to which it was born, and of the true nature of the evil, and of what is its own proper possession, and what is none of its own concern. And whenever some one of these things that are none of its own concern is in a bad way, it says, "Woe is me, for the Greeks are in danger." Ah, miserable governing principle, the only thing neglected and uncared for! "They are going to perish, slain by the Trojans." But if the Trojans do not kill them, will they not die anyway? "Yes, but not all at once." What difference does it make, then? For if death is an evil, whether they die all at once, or die one at a time, it is equally an evil. Nothing else is going to happen, is it, but the separation of the paltry body from the soul? "Nothing." And is the door closed for you, if the Greeks perish? Are you not permitted to die? "I am." Why, then, do you grieve? "Woe is me, a king, and holding the sceptre of Zeus!" A king does not become unfortunate any more than a god becomes unfortunate.
