Everyone was frantically searching for their name, colliding with each other, pushing around others and there was utter chaos. At the end of the 5 minutes no one could find their balloon. Now each one was asked to randomly collect a balloon and give it to the person whose name was written on it. Within minutes everyone had their own balloon.
The speaker began: exactly this happens in our lives. Everyone is frantically looking for happiness all around, not knowing where it is. Our happiness lies in the happiness of other people. Give them their happiness, and you will get your own happiness. And this is the purpose of human life.
