True happiness is such a rare commodity(有价值之物)that the whole of the world is continuously seeking it and failing to find it. Why is happiness such an elusive(难捉摸的) thing? Is it that it cannot simply be achieved? Or is it that it is not where all of us have been looking for it?

What is it that we consider happiness? This is how I see it: Happiness is what you feel when what you want to happen happens. And the then we can conclude that unhappiness is what we feel when what we want to happen does not happen.

The main keyword in definition is "want". The whole trouble starts when we want something. Every moment of our lives we keep on wanting something or the other. Only a small percentage of all our wishes is fulfilled in spite of all our endeavors(努力). The frustration of failing to fulfill most of our wishes sets in. We start feeling weighed down. Desire is a seed which grows fruits of unhappiness. Actually the trouble is that we demand too much. The only solution to this problem is to break out of this cycle of desires and struggles.

Actually, happiness and unhappiness are two sides of the same coin. The desire for happiness is like asking only for the light and not for darkness. But there is not much difference between light and darkness. It is matter of degree only.

If we think deeper, we will realize that it is this pain of failure, pain of frustrated desires which is of greater significance to us. It is actually like good health. One can only define health as an absence of diseases. In order to have good health we strive to avoid diseases. You cannot purchase or achieve good health directly. You have to take steps which keep your body free of diseases. Then only the organs of body keep functioning properly and you experience good health. Similarly, when one destroys the root cause of unhappiness, the problems are over. And the root cause of all our unhappiness is DESIRE.
