Essentially, what the average person wants out of life is just one thing: happiness. It is in this quest that he goes through life day after day in the firm belief that he will somehow, someday find final satisfaction through the things and circumstances of his world. There comes a time, however, when man gets utterly tired, physically and mentally, of this constant search because he finds that it never ends. He comes to the startling discovery that every kind of satisfaction has within itself the roots of pain and torment. At this stage his search cannot but take the turn inwards toward that happiness which is independent of external things.
