According to kabbalistic tradition, this day marks the "hillula" (celebration, interpreted by some as anniversary of the death) of Rabbi Shimon bar Yochai, "the Rashbi", a Mishnaic sage and leading disciple of Rabbi Akiva in the 2nd century, and the day on which he revealed the deepest secrets of kabbalah in the form of the "Zohar" (Book of Splendor, literally 'radiance'), a landmark text of Jewish mysticism. This association has spawned several well-known customs and practices on Lag BaOmer, including the lighting of bonfires, pilgrimages to the tomb of Bar Yochai in the northern Israeli town of Meron, and various customs at the tomb itself. However, the association of Lag BaOmer with the death of Rabbi Shimon bar Yochai may be based on a printer's error.
