It states in the sefer מירון מסע that in Cheshvan 1761/ב"תקכ, there was an earthquake in Tzefas and Miron, and many Arabs, with their wives and children, ran to the building over Reb Shimon’s grave for protection, but the door was locked. They shouted, "Reb Shimon! Reb Shimon! We heard about your greatness from our fathers and witnessed it with our eyes. Open your doors." Miraculously, the doors opened, and they went inside. Reb Shimon became even more revered by them at that time.
A month later, on the 6th of Kislev, there was a second earthquake. Yidden and lehavdil goyim ran to Reb Shimon’s grave. They found the building jumping up and down. The dome on the roof split in two. They became very afraid. They shouted, "Reb Shimon! Reb Shimon! If this is happening to your building, what will be with us?" Finally, after a half hour, the earthquake settled, and the building sat firmly in place. They went inside to inspect the damage, but there were none. The dome merged, and there was no sign of any scratches or damage.
Once, someone came to Rebbe Dovid Biderman zt’l for a brachah for his sick son. Rebbe Dovid Biderman advised him to daven in Meron. The man replied, "I was already in Meron, and my son is still ill." Rebbe Dovid Biderman told him, "When a person goes to a doctor once and isn’t healed, does he stop going to the doctor? No! He goes again. If a person takes a medication once and it doesn't help, does he give up? No! He tries again. I advise you to go to Meron repeatedly until your son has a refuah sheleimah."
Lag b'Omer teaches us never to lose hope: The Beis Yosef tells us that we celebrate Lag b'Omer because Reb Akiva's students stopped dying that day. The Pri Chadash claims that this isn't a reason to celebrate. The students stopped dying when no more students were left! Instead, the Pri Chadash explains, we are celebrating the continuity of the Torah. On this day, Reb Akiva took his five remaining students: Reb Meir, Reb Yehudah, Reb Yossi, Reb Shimon, and Reb Elazer ben Shamoa and taught them Torah. He made them the future leaders of Bnei Yisrael, which is how the Torah survives today.
Reb Akiva lost most of his students but didn’t give up. Instead, he forged ahead and did what he could, and that's how Torah continues until today. We, too, shouldn't lose hope in tefillah and for aspiring for our salvation. Everything is in Hashem's hands. If we davened once, we should daven again until we attain our salvation.
A father came to Rebbe Dovid Biderman of Lelov zy'a and told him that his son was acting improperly and that he kept taking off his yarmulke. Rebbe Dovid Biderman advised them to bring their son to Meron on Lag b'Omer. The father followed this counsel, but it was a very embarrassing trip for him. The child kept throwing off his yarmulke, and at every stop, they had to look for the child before continuing their way because he kept wandering off. In Meron, they lit the fire, and the Rebbe took the boy's yarmulke and threw it into the fire. The boy shouted, "My yarmulke! My yarmulke!" His attitude changed in a minute. Before that, he was constantly throwing off his yarmulke, and now he wanted it.
In the beis medresh of Reb Aharon of Belz zt'l on Lag b'Omer, many candles were lit on the tables and the windowsills. (This was done in Belz only on Lag b'Omer and on the 7th of Adar.)
A car hit the three-year-old son of someone I know before Pesach, 5766. After Pesach, the hospital sent the unconscious child to a nursing facility, saying there was nothing else they could do for the child. Two weeks before Lag b'Omer, the parents went to Meron and proclaimed before Reb Shimon's holy tzion, "We wanted to bring our son here on Lag b'Omer to make his chalakah" and davened that they should merit this. We won't elaborate, but two weeks later, on Lag b'Omer, the boy was in Meron, walking on his own two feet, and had his chalakah there.
