Reb Shimon said about Lag b'Omer, האי קאי ברשותי יומא, "This day is mine." Hashem gave this day to Reb Shimon, and therefore, many miracles occur on this day. Indeed, tzaddikim called Lag b'Omer "Reb Shimon's day."
The Zohar (Idra 296) says that when Reb Shimon was buried in Meron, a bas kol announced, "In your merit, many kitrugim [harsh decrees] are silenced on this day." This occurs every year on Lag b'Omer. It is a day when the kitrugim are silenced, and Hashem sends salvations to Bnei Yisrael. As we wrote above, Beis Aharon writes, אפילו לכל י"רשב הוא י"רשב כך לכל 'ה הוא ת"שהשי כשם לפחותים, "Just as Hashem is for everyone, so is Reb Shimon for everyone, even for those who are at a low level."
לכל, "for everyone," can also be translated as "for everything" because on Lag b'Omer, a person can receive everything he needs.
26. Yea 5695: The Ahavas Yisrael of Viznitz’s children arrived in Meron on Lag b'Omer. Someone shouted, "Make room for the Viznitzer Rebbe's children!" An old lady shouted back, "Near Reb Shimon, we are all children."
The Imrei Chaim zt'l of Viznitz would often repeat her words. "We are all Reb Shimon's children." A father has compassion for his children, even when they don't deserve it. This is why Reb Shimon is for everyone, even those at low levels.
When Rebbe Avraham Elimelech of Karlin hy’d zy’a was in Meron, he didn’t take kvitelach from his chassidim. He told them that in Reb Shimon's merit, everyone has an exceptional power of tefillah. Similarly, Rebbe Moshe Mordechai of Lelov zy’a would go with his chassidim to Meron for Shabbos parashas Behaloscha and wouldn’t accept kvitelach from them, as he felt that there was no need. In Reb Shimon's merit, everyone would undoubtedly receive their salvation.
Rebbe Avraham Elimelech zt'l and Rebbe Moshe Mordechai zt'l both said that after going to Meron, there is no need to go to any other kever. Rebbe Avraham Elimelech zy’a said: "After pouring one's heart out in Meron, one should have the sensation that he left all his troubles in Meron with Reb Shimon."
There are many large stones on the mountain going up to Reb Shimon’s kever. Tzaddikim said that these are the heavy stones people shed from their hearts while praying in Meron.
27. The Tur (428) teaches that Lag b'Omer is always on the same day of the week as Purim. About Purim, it states לו נותנים יד הפושט כל that whatever one asks for on this day is given to him. The same applies to Lag b'Omer. It is a special time for tefillah. Whatever one requests will be given to him.
The Kozniter Magid zt'l (Tehilas Yisrael, Tehillim 42) writes, "The entire Sefirah we wait for Lag b'Omer because on that day, there is a lot of rachamim." Lag b'Omer is a day of salvations – fortunate are those who invest in tefillah on this day.
Here are a few recommendations of what one can daven for on this holy day:
1] Children
Lag b'Omer is mesugal for the barren to bear children. The Midrash (Shir HaShirim Rabba 1) states: A person from Tzidon, Eretz Yisrael, married a woman and waited ten years for a child, but she still did not bear one. They came to Reb Shimon bar Yochai and told him they wanted to divorce.
Reb Shimon replied, "I swear, just as you got married with food and drink, you should divorce amidst food and drink."
They made a big meal, and she gave him a lot to drink. He told her, "My daughter, take any good item you wish and bring it to your parent's home."
He fell asleep, and the wife motioned to her servants to carry her husband to his bed to her parent's home.
In the middle of the night, he awoke. The wine had worn off. "My daughter, where am I?" he asked.
She told him that he was in her parent's home.
"Why am I in your parent's home?"
She said, "Didn't you tell me I can take anything I want to my parent's home? There is nothing that I want in the world more than you!"
They returned to Reb Shimon bar Yochai, he davened for them, and they had a child. In this story, Reb Shimon helped a barren couple bear children, and such a miracle can also occur now, in Reb Shimon's merit. Therefore, Lag b'Omer is a mesugal time to daven for children.
The Midrash concludes, "Hakadosh Baruch Hu helps the barren, and so do tzaddikim."
