"There is another sense in which life is often sorrow, but a kind of sorrow that can be entirely avoided. The man who lives the ordinary life of the world often finds himself in trouble of various kinds. It would not be true to say that he is always in sorrow, but he is often in anxiety, and he is always liable at any moment to fall into great sorrow or anxiety. The reason for this is that he is full of lower desires of various kinds, not at all necessarily wicked, but desires for lower things; and because of these desires he is tied down and confined. He is constantly striving to attain something which he has not, and he is full of anxiety as to whether he will attain it; and when he has attained it, he is anxious lest he should lose it. This is true not only of money but of position and power, of fame and of social advancement. All these cravings cause incessant trouble in many different ways."
