If thou art pained by any external thing, it is not this thing that disturbs thee, but thy own judgement about it. And it is in thy power to wipe out this judgement now. But if anything in thy own disposition gives thee pain, who hinders thee from correcting thy opinion? And even if thou art pained because thou art not doing some particular thing which seems to thee to be right, why dost thou not rather act than complain?—But some insuperable obstacle is in the way?—Do not be grieved then, for the cause of its not being done depends not on thee.—But it is not worth while to live if this cannot be done.—Take thy departure then from life contentedly, just as he dies who is in full activity, and well pleased too with the things which are obstacles.
Remember that the ruling faculty is invincible, when self-collected it is satisfied with itself, if it does nothing which it does not choose to do, even if it resist from mere obstinacy. What then will it be when it forms a judgement about anything aided by reason and deliberately? Therefore the mind which is free from passions is a citadel, for man has nothing more secure to which he can fly for, refuge and for the future be inexpugnable. He then who has not seen this is an ignorant man; but he who has seen it and does not fly to this refuge is unhappy.
Say nothing more to thyself than what the first appearances report. Suppose that it has been reported to thee that a certain person speaks ill of thee. This has been reported; but that thou hast been injured, that has not been reported. I see that my child is sick. I do see; but that he is in danger, I do not see. Thus then always abide by the first appearances, and add nothing thyself from within, and then nothing happens to thee. Or rather add something, like a man who knows everything that happens in the world.
