The Chofetz Chaim was impressed by her desire to honor talmidei chachamim, and he blessed her with (1) a long life, (2) always to have a clear mind, and (3) never to need eyeglasses. (The Chofetz Chaim understood that her eyes must be weak since she checked the rice near the window to catch the sunlight.)
All of the Chofetz Chaim's brachos materialized. She never needed eyeglasses and lived in good health until she was niftar at ninety-eight years old. She was always healthy, but on the last day of her life, she wasn't feeling good. She went to the hospital, and before they could examine her, her neshamah had already gone up to heaven.
This girl was an orphan, and when she came of age, the Chazon Ish was her shadchan, and she married the gaon, Reb Mordechai Shraga Feivel Eidelman zt'l. The Chazon Ish moved to Eretz Yisrael, and so did the Eidelman couple, who settled in Petach Tikvah.
Sixteen years had passed since her wedding, and they were still childless. She went to the Chazon Ish, together with the Chazon Ish's Rebbetzin, and expressed her distress that she still didn’t have children. The Chazon Ish gave her a brachah.
She said, "I don’t want a brachah; I want a promise that I will have children."
The Chazon Ish lowered his head into his hands, and when he raised his head, he said, "I can't promise you that."
She said, "I was an orphan, and you were my shadchan. Now you must take responsibility for the shidduch."
The Chazon Ish put his head down again, and when he raised it, he said, "For this, you need the strength of a gadol. Go to the kever of the Or HaChaim HaKadosh, and there you will have your yeshuah."
It was in 5704, and she told the Chazon Ish that it wasn't safe to go to Har HaZeisim. The Chazon Ish replied, "I have no other solution."
On the fifteenth of Tamuz, the Or HaChaim's yahrtzeit, she went to the Or HaChaim's kever at two in the morning together with her relative, the Rebbetzin of Reb Beinish Finkel zt'l. They poured out their hearts and prayed for a child. Precisely nine months later, on the 25th of Nissan, she had a son.
In 5773, a great rosh yeshivah lost his eyesight, and doctors told him he would never see again r”l. He asked his students to bring him to the kever of the Or HaChaim. At the kever, he vowed to learn Or HaChaim, as this is a renowned segulah for yeshuos. Some days later, he went to the hospital again, and this time, the doctors discovered that the part of his brain connected to his eyesight began functioning again, which meant it was possible to restore his eyesight, and they succeeded in doing so.
One year, a day after the Or HaChaim's yahrtzeit, someone I know called to tell me about the salvation he had after accepting on himself to study the Or HaChaim’s commentary. For parnassah, he sells sefarim and had a stock of 250 sets of Or HaChaim, plus other sefarim, and was having a hard time selling them. This was causing him a financial loss. On the yahrtzeit, he traveled with some friends to the Or HaChaim's kever, and they were talking about how studying Or HaChaim is mesugal for yeshuos. He immediately made a kabbalah to study Or HaChaim, and the salvation came very soon afterwards. The next morning, someone called him and said that he needed a large quantity of sefarim. His first order was 250 sets of Or HaChaim!
Studying Or HaChaim is also mesugal for teshuvah. Whenever Reb Yaakov Yosef of Skver zt'l heard about a bachur who needed chizuk and was beginning to fall off the derech, he would advise that people learn with him Or HaChaim. He added that the section of Or HaChaim doesn’t necessarily need to discuss mussar or chassidus. Any piece of Or HaChaim can bring people to teshuvah and improvement.
The gaon, Reb Meir Arik zt'l, would study the entire commentary of the Or HaChaim each week. He said that the first time he finished the entire sefer, he felt he had become a new person.
