I wrote under the topic Purim Question;
The Chidushei Harim has an interesting idea about drinking on Purim. A man collected and set aside a lot of money to do an averoh. He met a very poor family who needed the money. Having mercy on them, he completely forgot why he put aside the money and gave it to them. The heavenly court became very impressed with his deed and decided to grant anything he wished. They became afraid that he will wish something that they are not ready to grant him, the redemption. So, they decreed that his whole life he will have to be drunk to be out of his mind. Purim is a very sacred day where they grant any wish כל הפושט יד נותנים לו whoever stretches up his hand is granted whatever he wants. We can ask for the redemption but it might not be time yet, so the chachomim decreed to be drunk this day.
