Here is another example of someone who experienced yeshuos by being happy on Shabbos.
One Friday morning, after his checkup, the doctor told him, "Your suspicions were correct—you have a kidney stone. And not just one. You have three kidney stones piled on top of each other. The bottom stone is size 6, above it is a size 4 stone, and the top stone is size 2. We'll give it a couple of weeks; maybe things will improve. However, if they don't, we will need to operate."
It was hard for this yungerman to be happy that Shabbos due to his pain and his fear of surgery. His melancholy feelings affected the mood in his home. No one wanted to sing zemiros, and the delicious Shabbos food tasted bland.
But suddenly, the yungerman jumped up from his seat and grabbed a Gemara Bava Metzia. He opened it to Daf 25 and, with a shining face, repeated the Gemara numerous times. His family watched on in amazement, not understanding how his mood changed so quickly.
After studying the Gemara a few times, he told his family, "The Gemara discusses a case where someone found three coins of different sizes, one on top of the other. The largest coin was at the bottom, a medium-sized one in the middle, and a tiny one on top. The Gemara rules that it is evident that these coins didn't fall in this manner. Someone must have placed them there intentionally. Therefore, the finder must announce his find because the formation is a siman.
"I suddenly remembered this Gemara and realized that my kidney stones are in the same formation: the largest stone at the bottom, the medium in the middle, and a small stone on top. As the Gemara explains, this formation means the stones didn't reach there by chance. Obviously, they were placed there purposely by Hashem. And since it is from Hashem, I know it is for my good. Now I can be happy."
A week later, the stones left his body naturally. The joy of Shabbos brought him a remedy.
