The one who has no respect for himself, has no respect for others. He may think for the moment that he is regardless of conventionalities and free in his expression and feeling, but he does not know that it makes him as light as a scrap of paper moving hither and thither in space, blown by the wind. Life is a sea, and the further one travels on the sea the heavier the ship one needs. So for a wise man, a certain amount of weight is required in order to live, which gives balance to his personality. Wisdom gives that weight; its absence is the mark of foolishness. The pitcher full of water is heavy; it is the absence of water in the pitcher which makes it light, like a man without wisdom who is light-hearted.
