Once there was a king who wanted to appoint his prime minister in the kingdom. But there was none suitable in his eyes and also people in the kingdom could not able to select a person for the prime minister. So the king made one plan and declared that he had one lock which was not unlocked. One who could unlock it would be the prime minister of the kingdom. There were three persons for the competition. The king handed one big lock which was around 20kg weight. The first person came with lots of big keys and tried to unlock that. His whole labour went to end without any fruitful result. The next was one magician who came and tried to unlock that with lots of tricks but was unable to unlock that. The last person came without any keys and simply gave smiling to the audience and asked for their blessing for the competition. Then he held the lock for a moment and examined it and became surprised to see that the lock was unlocked before. He could not believe his eyes and went to the king to show unlocked one. The king became so happy by the third fellow and appointed as his prime minister.
