The answer is this: if a person who lives in poverty is given all the money he wants, is he then perfectly happy? Or a sick man may have become well again, but is it enough for him to be well or does he want more? This shows that man is always searching for something, he does not know what. And when he tries to find out what he is looking for he thinks that it must be the thing which he lacks in life. But if that which was lacking is given to him, then he wants something else. Well, this shows that it is not only greed or a defect in man; it indicates a great mystery in his soul, and that mystery is that the soul of man has all that it needs, and yet it has lost it. The story of Adam's exile tells us of this: by the exile of man is meant that which man lacks in life.
