for a tree, then for a man, then for something else; and each of these things subsists for a very short time. But it is no hardship for the vessel to be broken up, just as there was none in its being fastened together.
A scowling look is altogether unnatural; when it is often assumed, the result is that all comeliness dies away, and at last is so completely extinguished that it cannot be again lighted up at all. Try to conclude from this very fact that it is contrary to reason. For if even the perception of doing wrong shall depart, what reason is there for living any longer?
Nature which governs the whole will soon change all things which thou seest, and out of their substance will make other things, and again other things from the substance of them, in order that the world may be ever new.
When a man has done thee any wrong, immediately consider with what opinion about good or evil he has done wrong. For when thou hast seen this, thou wilt pity him, and wilt neither wonder nor be angry. For either thou thyself thinkest the same thing to be good that he does or another thing of the same kind. It is thy duty then to pardon him. But if thou dost not think such things to be good or evil, thou wilt more readily be well disposed to him who is in error.
Think not so much of what thou hast not as of what thou hast: but of the things which thou hast select the best, and then reflect how eagerly they would have been sought, if thou hadst them not. At the same time however take care that thou dost not through being so pleased with them accustom thyself to overvalue them, so as to be disturbed if ever thou shouldst not have them.
Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.
