Actual Practicle experience.
Once a group of 50 people was attending a seminar.
Suddenly the speaker stopped and started giving each one a balloon. Each one was asked to write his/her name on it using a marker pen. Then all the balloons were collected and put in another room.
Now these delegates were let in that room and asked to find the balloon which had their name written, within 5 minutes. Everyone was frantically searching for their name, colliding with eachother, pushing around others and there was utter chaos.
At the end of 5 minutes no one could find their own balloon.
Now each one was asked to randomaly collect a balloon and give it to the the person whose name was written on it.
Within minutes everyone had their own balloon.
The speaker began--- Exactly this is happening 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, you will get your own happiness.
And this is the purpose of human life.
Is this not what you are looking for?
