Some say that happiness is not good for mortals, and they ought to be answered that sorrow is not fit for immortals and is utterly useless to any one; a blight never does good to a tree, and if a blight kill not a tree but it still bear fruit, let none say that the fruit was in consequence of the blight.
The lives of happy people are dense with their own doings -- crowded, active, thick. But the sorrowing are nomads, on a plain with few landmarks and no boundaries; sorrow's horizons are vague and its demands are few.
Jesus, Buddha, Mohammed, great as each may be, their highest comfort given to the sorrowful is a cordial introduction into another's woe. Sorrow's the great community in which all men born of woman are members at one time or another.
Sorrow has the fortunate peculiarity that it preys upon itself. It dies of starvation. Since it is essentially an interruption of habits, it can be replaced by new habits. Constituting, as it does, a void, it is soon filled up by a real horror vacuum.
