A scientist was working on an important project and his children were disturbing him. So that he could work in peace, he tore a page which contained a world map into pieces and and gave them to the children saying: "I tore this world map by mistake. Would you please put it together and bring it to me?".
The children ran out with those pieces and the scientist took a sigh of relief thinking he could now concentrate on his work. But lo and behold, the children returned within no time. The world map was nicely stuck together. The scientist was astounded and asked the children how they could do this so swiftly?
Simple, they answered: behind we saw there was a picture of a man.. When the picture of the man was complete, the world map on the other side was complete.
The moral of the story: In all that we do, we must work for the welfare of man (meaning the lowliest) and the world will be in place (meaning peace will prevail).
