Rabbi Moshe Chaim Luzzato writes in “The Way of G-d”:
…Purim involved Israel being saved from destruction during the Babylonian exile. As a result of this they reconfirmed their acceptance of the Torah, this time taking it upon themselves forever. Our Sages teach us that “they accepted the Torah once again in the days of Achashverosh”. The details of the observance of both these festivals are related to the particular rectification associated with them.
To accept the Torah on Sinai we needed to be united as if the entire nation was “One Man with One Heart”. On Purim, when we re-accept the Torah, we once again achieved that unity in the face of annihilation.
The mitzvos of the day, charity to the poor, giving gifts of food, a meal with family and friends give us actions leading to achdus.
Adding achdus in thought and emotion is also important. Here are three ideas:
– Focus on the successes of our local institutions who are there to serve us.
– Support those dedicated to teaching and spreading Torah.
– Try to emotionally connect to our family, friends and community members who share our common spiritual purpose.
