“A lot was cast before Haman, concerning every day and every month, (until it fell on) the twelfth month, that is, the month of Adar.” (Esther 3:7)
Rav Gedaliah Schorr points out that since the Jewish months are counted from Nissan, Adar is the final month of the year. On a spiritual level, Nissan represents renewal. It is the beginning of a new year and the first month of spring, when the earth begins to awaken from its winter slumber. It is full of potential and energy, and for that reason, it was chosen as the month for the redemption from Mitzrayim.
The further a month is from the source of light, the darker and more hidden it will seem. For this reason, Haman was ecstatic at the choice of Adar, the last month of the year and not surprisingly the month in which Moshe was taken from us, as the most auspicious time for the annihilation of the Jews.
However, Rav Schorr explains that within the apparent concealment, a pool of light is hidden away. In fact, this source must be even stronger than at other times in order to allow it the ability to penetrate the darkness and not be completely swallowed up. In the midst of the great darkness, the month of Adar contains within it a tremendous source of radiance. When the Jewish people were inspired to properly repent, they were able to access and reveal this brilliant light, reversing all of the negative energy into forces for good. This potential energy is present every Adar, available and waiting for us to tap into it in order to reveal the ultimate light.
