Dovi, a bochur in a Yeshiva in Lakewood, New Jersey,* was preparing for his faher to get into a different Yeshiva. He needed his notebook to help him prepare but he couldn’t find it. He searched for it for over 3 hours. He asked other bochurim to help him. They checked everywhere but to no avail. It had disappeared.
Finally, a bochur suggested to Dovi that he should sing Hakol Yachol. He did so, but he still couldn’t find the notebook. So the bochur told him to sing it again this time with more kavana and to promise that if he finds it he would publicize it in the Spring Hill Times.
Dovi went into the Otzar Hasefarim where it was quiet to sing Hakol Yachol.
The second he finished singing, he looked up and there it was. In a place that he had searched already a few times before! [Heard from Dovi’s friend]
