Purim Secrets
Purim celebrates the salvation of the Jews from the wicked Haman’s scheme to exterminate all the Jewish men, women, and children living in the Persian Empire in the year 357 B.C.E., which essentially meant all the Jews in the world. Some of the commandments of Purim, such as hearing Megillat Esther, which recounts the Purim story, and enjoying a festive meal, are obvious ways to commemorate this deliverance.
Other commandments and customs have no apparent connection to what happened on Purim. Why are we required to give charity to the poor, send two food items to a friend, and get so drunk that we do not know the difference between Haman, the villain, and Mordechai, the righteous hero of the story? (This last commandment, I understand, is very rigorously kept in college dorms all year round.)
