Years ago, I lived in a building in a large city. The next building only was a few feet away from mine. They was a woman lived there, and I had never met her, yet I could see she sat by her window each afternoon, drinking or reading.
After a few months, 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 clean her window. It really looks terrible.”
One sunny morning I decided to clean my house, including washing the window.
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 clearly visible (看见). Her window was clean!
It dawned on me. I had been criticizing (批评) her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at others through the dirty window of my heart?
Since then, whenever I wanted to judge (评判) someone, I asked myself first, “Am I looking at him through my own dirty window?” I try to clean the window of my own world so that I may see the world about me more clearly.
