Lag BaOmer by DBLThe 50 days between Passover celebrating freedom from slavery and Shuvuos celebrating freedom for revelation, are known as sefirath ha-omer where each evening Jews count up towards Shavuot, noting the exact day of the omer within the Jewish Calendar. Rambam summarizes how the omer was designated [Rambam, Hilchot Temidin uMusafin 7:11] by a ceremony that elevated the sheafs of barley to a spiritual offering by the priests in the Temple which Jews still mourn and wish to be restored in the messianic age so that the heavenly temple of the afterlife be brought down in Jerusalem. Besides this literal agricultural context of the korban ha-omer, there is a spiritual and mystical dimension of the counting of the omer, that relates Pesah to Shavuoth and the mystical number of 50 days in between, correlating to Ramban’s notion of the Grand Yovel and what the Rashbi song sung on Lag Ba’omer refers to as the secret of 50. In recent times environmentalists relate the omer to to an environmental eco friendly-ethic of care.
Rabbi Akiba and the Plague
In the 2nd century CE, there was a plague that killed 40,000 disciples of Rabbi Akiba. The Talmud shares that this plague is punishment for their not showing proper ethical gravitas, or derekh eretz ( virtuous behavior ), towards each other.
Rabbi Akiba had five disciples who survived the plague. One of them, Rabbi Shimon bar Yochai, known as the Rashbi, went into hiding in a cave to escape persecution by the Romans, eating only carob, with his son to whom he transmitted mystical teachings. It was on Lag BaOmer that Rashbi left the cave. The Rashbi later would ascend to heaven, on Lag BaOmer, making Lag Ba’omer, a day of commemoration.
The "last words" of the Rashbi are in the section of Sefer HaZohar known as Idra Zutra. `There' the Rashbi prepares his disciples to join him in olam ha-bah (this world is a prosdur (vestibule) to olam ha-bah). Rashbi engages in mystical techniques of unio mystica to `marry' the Shekhinah (divine presence of G-d) whereby his talmidim are enjoined to prepare their souls also "to enter the metrakalin (banquet hall). Rambam rejects such anthropomorphism.
The 16th century mystics of Safed such as HaAri HaKodesh would make pilgrimages to Meron, the resting place of the Rashbi, and prostrate to effect cosmic theurgic unifications by reciting the Rashbi’s torah, “causing the lips to move,” and with great concentration (kavanah) recite basic texts such as the shema, 10 commandments, an mishnah (the textual incarnation of the Shekhina according to Rabbi Yosef Karo, Magid Mesharim).
As the power of Hebrew music in the Jewish arts testifies, song epitomizes the transcendence of the spiritual over the physical, please enjoy some music associated with Lag BaOmer. The custom of some is to listen to music again after the 33 days of mourning associated with the passing of 40,000 of Rabbi Akiva’s disciples who died from the plague, caused for not showing proper respect to one another.
