A man kept gold in a treasure chest which he buried under a floorboard.
The man died, and then a year later the man's son had a dream: he saw a mouse running back and forth, weeping pitiably.
"What's wrong, mouse?" he asked.
The mouse replied with his father's voice! "I still crave the gold I buried here."
"Father," said the son, "how did you become a mouse?"
"That is what happens to misers like myself," the mouse replied. "Have pity on me, and take care to avoid my fate: renounce the love of gold now while you still can."
