חייב איניש לבסומי בפוריא עד דלא ידע בין ארור המן לברוך מרדכי
A person is obligated to get drunk on Purim to the point that they don’t know the difference between “Cursed is Haman” and “Blessed is Mordechai”
The mitzvah to get drunk on Purim is quite surprising. It is well-known that getting drunk can easily lead to inappropriate behavior. Why was this instituted on Purim? As well, what relevance is the idea of “Cursed is Haman” and “Blessed is Mordechai”? Why is our getting drunk dependent on it? To begin to answer these questions, another halacha needs to be examined. There is an obligation on Purim to say the words “ארור המן ברוך מרדכי”, “Cursed is Haman; Blessed is Mordechai”. Why is this formulation unique to Purim? There are other festivals where we were saved by our leaders from our enemies. Why don’t we say on Pesach: “Cursed is Pharaoh; Blessed is Moshe”? Or on Chanukah: “Cursed are the invaders; Blessed are the Hasmoneans”?
