A man opened a centrally located store in the middle of a successful business area, but this store was not successful...
After half a year of losses the store was closed. A new business grabbed the location, but he was also not successful and closed it after half a year. Other businesses took over and all with the same result. This went on for a few years. All the businesses in the area thrived, but this store had a curse hovering over it.
My friend who owns businesses in most of the country and the world decided to take the store and open a business. However, he does not move a millimeter without consulting his Rav. He heard that this store had a curse, and he asked his Rav what he must do.
The Rav went down to the store and looked here and there, and told him, “Open your business here and you will be successful, just move the mezuzah to the other side, they placed the mezuzah on the wrong side!!!”
My friend opened the business and bli ayin hara was very successful, and only I remained speechless, how this mezuzah brought bracha to this business. If I may, people launch their stores and invest a fortune and even affix beautiful mezuzos, but never ask a Rav where to affix the mezuzah. Even in a house, I see people affix mezuzos in places that are not halachically correct, and so long as a Rav does not check it, they do not know why they are suffering.
Incidentally, I have another story. I have a friend who has a daughter who is often sick. He went to his Rav to ask for a bracha. The Rav told him to check the mezuzah in the bedroom of the girl. My friend replied that he had recently checked all the mezuzos of the house and they were all kosher l’mehadrin, Baruch Hashem, so he did not think this was the reason. The Rav who is a holy person, told him to bring him the mezuzah and he would check it. My friend went and removed the mezuzah from his daughter’s bedroom, and then he was gripped with trembling. True, the mezuzah was checked and was indeed kosher. But by mistake he put the mezuzah back in the case upside down... He immediately turned the mezuzah right side up and replaced it as per halacha and amazingly, overnight his sick daughter became healthy!!!
