     Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her sit by her window each afternoon, sewing(针线活) or reading.
     After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, "I wonder why that woman doesn't wash her window. It really looks terrible.”
     One bright morning I decided to clean my flat, including washing the window inside. Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was seen clearly. Her window was clean! Then it dawned on me. I had been criticizing(批评) her dirty window, but all the time I was watching hers through(通过) my own dirty window.
     That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own mistakes?
     Since then, whenever I wanted to judge (评判) someone, I asked myself first, "Am I looking at him through my own dirty window?”
Then I try to clean the window of my own world so that I may see the world about me more clearly.
