Lag Ba'Omer is one of the least known days on the Jewish calendar, which is not found in the Torah, yet has a major Kabbalistic and Talmudic significance. 

Known as the Hillula or wedding of Rabbi Shimon Bar Yochai, the greatest Kabbalist ever and author of the Zohar.

The Kabbalistic holiday of Log Ba'omer falls out during the week of Hod, which according to Kabbalah is the last rung on the Kabbalistic Sefirot chart. 

Hod means splendor, humility and acknowledgment, which according to Kabbalah are of the greatest importance.

Rabbi Shimon Bar Yochai and the Zohar causes an interconnection of opposites. This explains why according to the Talmud the students of Rabbi Akiva stopped dying.

More specifically, the Zohar says that Rabbi Shimon passed away on the day of Hod of Hod, which according to Kabbalah is the deepest level of acknowledgement and humility.
