I read recently about an old, rich man with a cranky, miserable attitude who visited a Rabbi. The Rabbi was a simple man whose heart was right and he lived a simple life. They weren't together very long before the Rabbi got a wonderful idea on how to illustrate to the man what was wrong. He took him by the hand and he led him over to his window and he said, "Now look out the window and tell me what you see."
The man stood there and said "Well I see some men and some women and I see a few children."
The Rabbi took him by the hand and led him across the room to a mirror and said, "Now look there and tell me what you see."
The man frowned and said, "Well, obviously I see myself."
"Interesting," the Rabbi replied. "In the window there is glass, in the mirror there is glass. But the glass of the mirror is covered with a little bit of silver. And no sooner is the silver added than you cease to see others, and only yourself." Maybe our troubles started when just a little bit of silver was added and we stopped looking through and starting looking at ourselves.
