Raghu has been orphaned when he was quite young so he had learned to fend for himself. One day he was very hungry. Wondering what to do, he happened to pass a sweet shop and heard the shopkeeper tell his young assistant, "Look after the shop while I take a nap. Call me only if something important comes up." Raghu smelt an opportunity. He waited for a short time and then entered. "I am the owner's best friend's son. Give me the best sweets in the shop." The boy was suspicious and asked him his name. "My name is Fly," said Raghu helping himself to some jalebis. As he sat eating, the boy ran to the owner, "Fly is eating the sweets. What should I do?" The sweet shop owner was in a deep sleep. He mumbled, "How much can a fly eat? Let him be." Then he turned over and started snoring loudly. The poor boy could do nothing but watch him demolish a plate of jalebis. Finally Raghu took two boxes of the best sweets in the shop and left without paying.
These boxes he presented to Mahadev saying, "Here is a present for our city's greatest man. Please accept this. I am a poor man and have nothing else to give you." Seeing the box full of expensive sweets Mahadev, who rarely parted with money, was delighted. "Sir", continued Raghu, "I have only one request. May I have the empty boxes back please?" Mahadev was only interested in the sweets so he said graciously, "Of course. Ask my wife to give you two vessels for the sweets." Raghu went to Mahadev's wife and said, "Your husband has asked you to give me two gold coins". The woman who was cooking lunch was astonished and said, "Are you out of your mind?" My husband would never say such a thing!" So Raghu called out to Mahadev, "Your wife is refusing to give me what I asked for." Mahadev was negotiating a handsome deal in his shop. Irritated by the disturbance he called out, "Give him what he wants." So Raghu left with the gold coins in his pocket.
Days went by and Raghu made his living through his smooth talk and tall promise. The king heard about this. Raghu was brought to him under arrest. The king heard to his story in silence and then said, "Since you are so clever study with the best pundits in the land. Use your wits for the betterment of the kingdom." Raghu was silent. No one had praised him or offered the King's terms and one day came to be known as one of the wisest of his ministers.
Why did Raghu visit the sweet shop?
