WHAT IS PURIM?
Purim (Adar 14th) celebrates the victory of Mordechai and Esther over the evil Haman. The story can be found in the Tanach (Hebrew Bible), in the Book of Esther, and it is read every year during the holiday. The word Purim means lots, becasue Haman cast lots to decide on what day he will destroy the hated Jews. Fate fell on the month of Adar, which is why, according to the Rabbis, "Mi schenichnas Adar, marbin b'simcha", When we enter the month of Adar, we increase our joy. There is nothing sacred in our celebration of victory. It is not accompanied by prohibitions as is usual with our pilgrimage holidays and although it is found in the Bible, it is not part of the Torah, thus it is a rabbinic holiday and not a Torah-based one.
