"Foolish people believe that happiness is the result of the external world and so they pursue that. You see, there is no chance of happiness if control is in the hands of others. If we invest all our hopes in achieving peace of mind and happiness in the external world, we will be under the control of the external world. We will be pulled this way and that, running to join this club, or running to buy that product. We spend so much money. And then we have to work the rest of the year to earn the money to be able to continually run this way and that. Finally, we die, exhausted, still unsatisfied."
