A shopkeeper sent his son to learn about the secret of happiness from the wisest man in the world. The boy walked a long way, and finally came upon a beautiful castle where the wise man lived.

Rather than finding a holy man, though, our hero, on entering the main room of the castle, saw a hive of activity: tradesmen came and went, people were chatting in the corners and a small orchestra was playing soft music. The wise man talked with everyone, and the boy had to wait for two hours before it was his turn.

The wise man listened carefully to the boy’s explanation of why he had come, but told him that he didn’t have time just then to explain the secret of happiness. He suggested the boy look around the palace and return in two hours.

“Meanwhile, I want to ask you to do something,” said the wise man, handing the boy a teaspoon that held two drops of oil. “As you wander around, carry this spoon with you without allowing the oil to spill”.

The boy began to walk up and down stairs in the palace, keeping his eyes fixed on the spoon. After two hours, he returned.

“Well,” asked the wise man, “Did you see the Persian tapestries (波斯织锦) hanging in my dining hall? Did you see the garden that it took the master gardener 10 years to create?”

The boy was embarrassed, and replied that he had observed nothing. His only concern had been not to spill the oil.

“Then go back and observe the wonderful things of my world,” said the wise man.

Then the boy picked up the spoon and returned to his exploration of the palace, this time observing all of the works of art on the ceilings and the walls. He saw the gardens and the mountains all around him. When he returned, he described in detail everything he had seen.

“But where are the drops of oil I gave to you?” asked the wise man. Looking down at the spoon he held, the boy saw that the oil was gone.

“Well, there is only one piece of advice I can give you,” said the wise man. “The secret of happiness is to see all the wonders of the world and never to forget the drops of oil on the spoon.”
