       Years ago, I lived in a building in a large city. There was another building not far from mine. A woman

  lived there. I had never met her, but I could see her sit by the window each afternoon, sewing (缝纫)or

  reading.

       After several months, I began to notice that her window was dirty. Everything was unclear through the

   dirty window. I would say to myself, "What a lazy woman! I wonder why she doesn't wash her window.

   It really looks terrible."

       One bright morning, I decided to clean my flat, including the windows. I worked the whole morning.

  When I finally finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a

  surprise! Everything in the woman's flat could be seen clearly. Her window was clean!

       I began to understand. I watched the woman's window from my own dirty window. That's the

  problem!

       That is quite an important lesson for me. How often do I look at and criticize others through the dirty

  window of my heart?

       From them on, whenever I want to judge someone, I ask myself first, "Am I looking at him through my

   dirty window?" Then I try to clean the window of my own world so that I may see others' world more

  clearly.
