Once upon a time, there lived four friends in an Indian village. All of them were quite jovial. One day, they were practising to shoot. They kept a few pots at a distance as their targets. None of them could hit even a single pot as they were talking and laughing all the while! They were very angry with themselves. A saint, who was watching them, started laughing. One of them went to him and asked, “Why are you laughing? Do you know how to shoot?” The saint took the gun and fired at the pots, smashing all of them one by one. They were amazed to see this and asked the saint if he was a magician. The saint replied, “I am neither a magician nor a sharpshooter. If we want to complete any task successfully, we have to concentrate on that task. I just concentrated and the result is in front of you. One should always work with great concentration.” They thanked the saint for the invaluable piece of advice.
