The celebration of Lag B'Omer on Mount Meron has become one of the biggest festival holidays in Israel. The biggest celebration takes place at Mt. Meron, the burial site of the sage and mystic Rabbi Shimon bar Yochai. According to tradition, on the day of his death, he revealed the deepest secrets of Kabbalah in the form of the Zohar (Book of Splendor), a text of Jewish mysticism. Today bonfires are lit all night and into the morning in celebration of the wisdom emanating from the rabbi. This day is also a break of mourning in the period between Passover and Shavuot. During this short break, three-year-old boys receive their first hair cut, couples may marry, and music may be played.
