Man is never satisfied with his life: he is for ever seeking something that is better. Until he learns wisdom, he looks for it in pleasure, in sense gratification of various kinds, in wealth, luxury and possession. The less evolved a man is the more convinced he is that happiness can be gained in these ways, and the lower are his desires. For instance, those who form what is called the underworld of our cities, seek happiness in vice and debauchery. Those who are more evolved seek pleasure in more refined things, hoping to find happiness in intellectual pursuits, friendships, and in pure human loves. These more evolved types get much more pleasure through the senses than do those who are more elemental, but they are capable also of greater and more acute suffering. They can derive great pleasure from a picture gallery, whereas a savage would see nothing interesting at all: they can also suffer from things which a savage would not be capable of feeling. Yet, in spite of this developed refinement and ability to derive pleasure from art, science, literature, etc., happiness is still as far off as ever. All attempts at finding happiness lead finally to "emptiness." There is no satisfaction, either in wealth and all that it can command, getting on in life, or in fame and power. They allure at first and promise happiness, but they fail us, and finally are seen to be but vanity and vexation of spirit. This desire for happiness is good, for it leads us through innumerable experiences so that the soul can realize, by practical experience, the emptiness of all self-seeking, and thus learn wisdom. After running the whole gamut of experience the soul learns at last that happiness is not something that can be found by seeking it, but is an inward mental state. Although work, well done, brings a quiet sense of satisfaction, and success in one's career may also be a source of gratification for a short time, yet even these cannot satisfy the deep longing of the soul. Happiness, however, is to be found in service. Not if we seek happiness in service, and serve in order to be happy, but if we serve others for the sake of serving we find the only happiness that will endure and satisfy. One has only to observe the lives of those who are always selfishly seeking and grabbing, who are hard in their dealings, and always "looking after number one," in order to see how impossible it is for self-seekers to be happy. It does not matter whether they acquire riches or remain poor--they are equally unhappy. In contrast to this, you have only to go out of your way to do a kind and perfectly disinterested action and experience the glow of sheer happiness that it brings, in order to realize that you are dealing with a law of life that is as sure and unalterable as the law of gravitation.
