Long long ago, there was an old merchant who had three sons. “To which one shall I leave my fortune?” he wondered. “It must be to the cleverest son. But which one is the cleverest?”
He called his three sons to him. “Here is some money,” he told them, “you must each take one coin to buy something that will fill this room. Anyone who can do this shall have my fortune.”
“It is a big room,” said the eldest son.
“One coin will not buy very much,” said the second son.
But the youngest son said nothing. He stood and thought, and then he smiled, “Come, brothers,” he said, “let us go to the market.”
The eldest son bought straw with his coin. But one coin bought only a bit of straw. Even when he had spread it as much as he could, the straw covered only a corner of the room.
The second son bought sand with his coin. But one coin bought only a bit of sand. Even when he had spread it as much as he could, the sand covered only half of the floor.
“What did you buy?” the eldest son angrily asked the youngest son. “You don't have any straw.”
“Yes, what did you buy?” the second son asked angrily. “You don't have any sand.”
“I bought this,” said the youngest son.
“A candle！” cried his brothers. “What good is a candle?”
“Watch”, said the youngest son.
He lit the candle, and all at once the room was filled from wall to wall, from ceiling to floor. It was filled with light!
“Although you are the youngest, you are indeed the cleverest of my sons,” the old merchant said.
And that is how, the old merchant left his fortune to his youngest son, the one who could fill a room with light.
