Whenever you take a step forward, you are bound to disturb something. You disturb the air as you go forward, you disturb the dust, the ground. You trample upon things. When a whole society moves forward, this trampling is on a much bigger scale; and each thing that you disturb, each vested interest which you want to remove, stands as an obstacle.
We notice that the mind is a restless bird; the more it gets the more it wants, and still remains unsatisfied. The more we indulge our passions the more unbridled they become. Our ancestors, therefore, set a limit to our indulgences. They saw that happiness was largely a mental condition. A man is not necessarily happy because he is rich, or unhappy because he is poor.... Millions will always remain poor.
