Once a circle missed a wedge（楔）. The circle wanted to be whole, so it went around looking for its missing piece. But because it was incomplete and therefore could roll only very slowly, it admired the flowers along the way. It chatted with worms. It enjoyed the sunshine. It found lots of different pieces, but none of them fit. So it left them all by the side of the road and kept on searching. Then one day the circle found a piece that fit perfectly. It was so happy. Now it could be whole, with nothing missing. It incorporated（组合）the missing piece into itself and began to roll. Now that it was a perfect circle, it could roll very fast, too fast to notice the flowers of talking to the worms. When it realized how different the world seemed when it rolled so quickly, it stopped, left its found piece by the side of the road and rolled slowly away.
The lesson of the story, I suggested, was that in some strange sense we are more whole when we are missing something. The man who has everything is in some ways a poor man. He will never know what if feels like to yearn（渴望）, to hope, to nourish（滋养）his soul with the dream of something better. There is wholeness about the person who has come to terms with his limitations, who has been brave enough to let go of his unrealistic dreams and not feel like a failure for doing so.
