The Month of Adar
Introduction
“When Adar enters, we increase joy.”
Our Sages tell us that on a birthday, one’s “spiritual power is predominant.” Consequently, on the birthday of a Leader of Jewry, the power of the entire nation is predominant. In the case of Jewry’s ultimate Leader, Moshe Rabbeinu, this predominance not only exists on the 7th of Adar—when Moshe was born—but throughout the month of Adar. For that reason, the Midrash considers it as if Moshe had been born on the 1st day of the month, which encapsulates the entire month.
During Adar, then, the power of Moshe Rabbeinu—and by extension, all Jewry—is predominant and manifested. In a leap year, when the month of Adar is repeated, both months contain this virtue, and both are celebrated with great—even doubled—joy.
