In a small town in Poland lived a storekeeper named Abraham. Though not at all a wealthy man, when it came to giving charity and offering hospitality to wandering Jews, he was without equal.
One day Abraham had an unexpected and distinguished visitor, his Rebbe. The Rebbe was impressed with the warm hospitality and attention Abraham showed him. But his keen eyes did not fail to note that Abraham went far beyond the call of duty in the mitzva (commandment) of hospitality to visitors and giving charity. And so, before leaving, the Rebbe blessed Abraham - that he be able to practice these mitzvot in comfort and riches.
Soon after the Rebbe left, Abraham noticed a change in his business affairs; a change for the better. Every day brought him better business and more prosperity.
But, riches can be as much a test as poverty and, without even realizing, it he began to find less and less time for the mitzvot he had always treasured so.
Abraham now lived in a beautifully furnished house, with several servants. Beggars were no longer admitted, though at the door they could still get a fairly handsome donation. People began to notice the change in their old friend.
One day Abraham was informed that a very persistent Rabbi wanted to see him. Abraham greeted the man curtly, but when told that he was sent by their Rebbe, Abraham's face lit up. "Ever since the Rebbe's visit to my house my fortune has taken a good turn, and, thank G-d, I have done well, as you can see." The Rabbi asked for help in freeing a man who had been imprisoned on false charges. Abraham quickly took out a substantial sum of money and gave it to the visitor to take to the Rebbe. While seeing him to the door, Abraham apologized to the visitor that he was too busy to spend more time. "Remember me to the Rebbe, please," Abraham said as he shook hands with him.
The Rebbe questioned his emissary closely about Abraham and his way of life, and it saddened him to think that Abraham had changed so. "Is it possible that my blessing could have been the indirect cause of this change?" the Rebbe wondered. He decided to pay a visit to Abraham.
Abraham welcomed his Rebbe on his arrival with joy and respect. "Quite a change from before, Rebbe," Abraham commented as he saw the Rebbe looking all around.
"Quite a change" the Rebbe agreed, his face quite serious. He came up to the window and looked out.
"Abraham, come here a minute," the Rebbe called. "Who is that man walking there?"
"That is Yankel the Tailor," Abraham replied, adding "a pious Jew. Unfortunately he is very poor..."
"And who is that woman carrying an empty basket?"
"That's a widow going to market...poor woman, and a houseful of orphans, too." Abraham began to wonder why the Rebbe had become so interested in the passers-by; he was not a man of idle curiosity.
The Rebbe turned away from the window and walked up to a large mirror. "Look into the mirror, Abraham. Whom do you see there?"
"Why, myself, of course," Abraham replied, puzzled.
"Tell me, Abraham. What is the difference between a window and a mirror?"
"That is quite simple," Abraham explained. "They are both glass but a mirror has a coating of silver on it."
"I see, I see..." the Rebbe said. "When you put silver on a piece of glass, you see only yourself. Extraordinary, isn't it?"
"Yes, indeed, but..." Abraham did not finish the sentence. Suddenly it dawned on him what the wise and saintly Rebbe was hinting at. Before he was "coated with silver" he could see everybody, but now that he had become rich, he could only see himself.
Abraham felt a deep sense of shame. "I've failed my test, haven't I Rebbe? Is there any way I can make it up?" he asked tearfully.
"You must return to your good old way of giving charity generously and graciously, and inviting guests humbly into your home - all in accordance with your ability."
Later Abraham went over to his mirror with a sharp knife. He scraped off the silver in one of the corners. In this way he would always be reminded not to see only himself.
