Rabbi Shimon Bar Yochai
Rabbi Shimon Bar Yochai also known as the Rashbi was a 4th generation Tana and a student of Rabbi Akiva, recognized even in his youth for his greatness in Torah. He was one of the five student to receive Smicha from Rabbi Yehuda ben Bava and later from Rabbi Akiva following the death of his students. After being sentenced to death for making a negative remark about the Roman government, Rebbe Shimon was forced to flee along with his son Rebbe Elazar, hiding in a cave in Peki'in for 13 years. Great mysteries of the Torah were revealed to the Rashbi during the years he spent in the cave and upon emerging he founded the school that created the Zohar, one of the pillars of the Kabbalah. Often quoted in the Mishna under the name 'Rebbe Shimon', he also authored the basis of the Sefri. Rabbi Shimon Bar Yochai is buried in Meron, his Kever being the most visited in the world, with over 600,000 visitors arriving to his Hillula on Lag Baomer. He is known to have been one of the five 'Tzadiki Yesod Olam' that existed throughout history.
Rabbi Shimon was the son-in-law of Rabbi Pinchas Ben Yair and possibly had a son-in-law with the same name. Meaning his daughter married the grandson of Rabbi Pinchas the Elder who was also named Rabbi Pinchas Ben Yair.
Atone for the World
Rebbe Shimon passed away on Lag Baomer, the 18th of Iyyar. On that day he revealed many great mysteries of the Kabbalah to his students and this event is known as the Idra Zuta - the Lesser Assembly, in contrast to the Idra Raba - the Greater Assembly, where more students were present.
Seat by Achiya HaShiloni
When Rebbe Shimon became ill, Rabbi Pinchas, Rabbi Chiya, Rabbi Aba and the Chavarim came before him. They heard Rabbi Shimon say something but he had disappeared and they could not see him. They wondered and none could utter a word due to the great fear that fell upon them. Suddenly they began to smell heavenly fragrances that strengthened them and once again they saw Rebbe Shimon. He was talking to someone but they saw no one besides him. Time passed and then Rabbi Shimon questioned his students if they had seen something. Rabbi Pinchas responded that they had not but were all wondering regarding his disappearance, the heavenly fragrances from the Garden of Eden and his conversation with an invisible entity. Rabbi Shimon responded that they had taken him Above and shown him the seats of the Tzadikim in the Next World but he was only satisfied when he selected his seat near the Prophet Achiya HaShiloni.
Stopping of the Sun
In middle of the Idra Zuta after noticing that the sun was setting Rabbi Shimon announced that "the day will not distance itself and settle in its place since the entire day is under his control",, therby holding the sun in place and preventing it from setting just like Yehoshua Bin Nun had done.
Day of Atonement
A the end of the Idra Zuta a heavenly Bat Kol voice came out and declared "how many prosecutors in Heaven have been silenced on this day in your merit". Many people that had large debts of horrible punishments and reincarnations were freed from judgment and saved from retribution in the merit of Rebbe Shimon Bar Yochai on that day.
Rabbi Shimon Bar Yochai's bed elevated itself and flew though the air and a fire burnt before it. All present heard a voice call out 'come to the celebration of Rebbe Shimon, may he come in peace and rest in his burial location.' When his bed entered the cave, they heard a voice from inside declare "This man uproars the land and upsets governments".
Cave of Rabbi Shimon
The cave where Rebbe Shimon hid with his son is located in Peki'in.
Kever Rebbe Shimon
Rabbi Shimon Bar Yochai is buried in Meron along with his son Rebbe Elazar. Their actual kever is in a cave which is now inaccessible but people pray at the tomb built above the cave with Matzevot aligned directly above the actual kivarim. Kever Rashbi is the most visited tomb in Israel with thousands of people streaming through each day during all hours. Historically many visitors to Eretz Yisroel would make trips to this location and recorded it in their dairies.
Even in Tanaic and Talmudic times Kever Rashbi was a renown spiritual shrine and the Talmud recorded an incident of it being visited by Rabbi Yehoshua ben Levi and Eliyahu Hanavi, which possibly occurred on Lag Baomer. The Zohar records the kever being visited by Rabbi Abba, Rabbi Chiya and one of Rabbi Shimons former students how had forgotten his learning, remembering it after weeping by the Kever.
Hillula of Rabbi Shimon
The hillulah of Rabbi Shimon Bar Yochai is celebrated each year on Lag Baomer. Over 600,000 attend the celebrations in Meron. Before he became well known the holy Arizal traveled with his entire family from Egypt, probably leaving right after Pesach, for the hillulah and spent three days in Meron.
There is great joy by the Hillula of the Rashbi and thousands of people dance in the courtyard and surrounding mountain slope. These joyous festivities were documented in many traveler dairies throughout the generations. Rabbi Avraham HaLavi was accustomed every day to recite the Nachem mourning prayers for the destruction of the Temple. After he recited them by the Tziyun during the Hillula, Rebbe Shimon appeared standing above his tomb to the Arizal and instructed him to inform Rabbi Avraham that since he had mourned during his day of joy, he would soon have reason to mourn due to the passing of one of his children.
There is an old custom to burn new expensive garments during the Hillula in honor of Rabbi Shimon. In the 1800's this custom came under controversy for transgressing the prohibition of 'Bal Tashchis' needless wasting of useful objects. Rabbi Shmuel Heller authored an entire book called 'Kavod Milachim' defending this custom. He brought testimony from the Sephardic Elders of Tzfat who witnessed Rabbi Chaim ben Atar (the Ohr Hachaim) himself burn valuable garments in honor of Rabbi Shimon in Meron on Lag Baomer.
Many people visit the tomb of the Rashbi on Zayin Adar for the Hillulah of Moshe Rabbenu since part of his soul was reincarnated in Rabbi Shimon Bar Yochai and both of them held the position of the Tzadik Yesod Olam who could associate with all Jewish souls.
The Great Collapse
For years people from all over the country would travel to Meron for the Hillula on Lag b'Omer. In the early 1900's various secular Russian immigrants began settling in the villages surrounding Meron. They too began coming to the Hillula despite their lack of Torah observance. In 1911 a group mixed singles arrived at the Hillula. Right after the lighting of the customary fire, the girls began to loudly and publicly sing Zionistic songs. At that moment a large wind swept the area, suddenly the upper balcony and wall collapsed throwing all the people and stones at the people who filled the courtyard. Ten people were killed and many people were injured. Leading Rabbis quickly pin pointed the reason on the lack of modesty that was occurring at the Hillula and decided to issue a temporary ban on women from visiting Meron on Lag Baomer. Despite the decision, no one had the audacity to publicly declare the ban, until this was done by Rabbi Yisroel Karduner.
