When people hear of a great new segula, they're very eager to try it, in many cases, even if it would cost them a lot of money or entail traveling. We have the greatest segula of all available to us at any time, free of charge. When a person prays to Hashem with real belief in His power and control, and a true feeling that He could easily help despite the hurdles that need to be overcome, that can produce the greatest salvations. When person A approaches person B for help, it can easily be detected if A really believes person B will help, or he's just going through the motions of asking. When a person really believes that Hashem is his best and only option, his approach will be different than when he thinks he has other options. A man told that both of his parents died young from heart conditions, רחמנא ליצלן . After he himself experienced certain sensations and symptoms in his heart , h e went to a doctor who determined that something was very wrong. He had a rare defect in his heart muscle, and to fix it, he would need to undergo a complex surgery by a world-renowned specialist, the only expert known for that type of issue. All of the people he spoke to told him the same thing. "If you value your life, make sure to do the surgery." This man lived in Israel, and would need to travel to Minnesota for the operation. He would have to rent an apartment near the hospital, then go for the surgery, and after recovery, go back to stay in that apartment. He would need to periodically go for checkups for up to six months after the surgery. In his mind, this meant a half a year in exile. What would be with his children? His wife would have to come along to take care of him. What would he do about minyan, about his shi'urim in Torah? What would become of his business? And where would he get hold of the astronomical sums needed for the surgery? He tried to get advice from anyone he knew in the medical field. He was advised to consult with a senior advisor who perhaps could find an alternate solution. He made the meeting and the advisor said, there is no other choice. "You must go to Minnesota as quickly as possible. Don't waste any more time. Your life is on the line." The man left there in a state of panic. He then went to shul to pray Arbit and heard the chazan saying, ה' צבאות עמנו משגב לנו - Hashem is with us and He supports us. At that moment, he was overcome with a feeling of bitachon in Hashem. The chazan continued, אשרי אדם בוטח בך. ה' הושיע המלך יעננו ביום קראנו - Hashem, save us, the King who answers us on the day we call out to Him. What a treasure. He had been saying those words all of his life but never fully appreciated them like he did at that moment. Hashem is the King of the entire world. With all of the doctors and all of the refuot, He is the only One who saves us. That Arbit was like Ne'ila on Yom Kippur for him. In fact, it was even more intense. He understood with all of his senses and bones that he is dependent only on the Chesed Hashem and that He is the only One with any say. He begged Hashem to heal him and spare him from six months in exile. After that, he still had to prepare in case he had to go. His wife was trying to work out the finances with his insurance company as well as all the other logistics of the trip to Minnesota. Meanwhile, he was becoming weaker and weaker. His heart was giving more and more warning signs. The surgery was scheduled for three weeks later in Minnesota and he continued to pray that Hashem give him a Refua Shelema right there in Israel. About ten days before the surgery, he received a call from his local hospital telling him the most amazing news. A very wealthy man with the same condition as him paid a huge sum of money to fly in the surgeon from Minnesota. He would be in the hospital there for 24 hours and they were hoping he would do his surgery as well. The hospital itself wanted all of their surgeons present to watch and learn from this man. The day came and the surgeon operated on him as well. It took only six hours instead of the eight that was expected. The surgeon told him it went extremely well. The man only had to be in the hospital for one week. He never had to leave his children or his minyan or his learning. Now, its 25 years later, and his heart continues to beat with tremendous gratitude to Hakadosh Baruch Hu for orchestrating those events the way he did. There is no segula like believing in the power of Hashem.
