He quoted the Chidushei Harim (the first Gerer Rebbe) who explains a reason for the mitzvah of drinking on Purim.
The Bal Shem Tov explained to his close followers that this person had done an unbelievable mitzvah of saving a girl, and the mitzvah of Pidyun Shevuyim (redeeming captives). The heavenly court, was so moved that it was decreed that whatever this person would ask for would be granted immediately.
The Chidushei Harim explained that on Purim there is a special law that anyone who extends his hand to you in need, must be given. But this is also true with regard to davening! For when we pray to Hashem on Purim, He HAS to answer our requests. So, to counter this unbelievable power of prayer, our sages legislated the law of drinking on Purim so that we don't use the day of Purim to pray for the wrong things! It is also wrong, says the Chidushei Harim, to NOT drink on Purim and to sit and daven all day, for by doing as such, one is going against the will of the sages, and will certainly not see blessing in his actions."
SO TODAY THEREFORE IS A REMARKABLE DAY WITH REGARD TO THE TREMENDOUS POWER OF PRAYER YET WITHOUT THE OBLIGATION TO DRINK, TO COUNTER IT!
LET US THEREFORE, USE THIS DAY TO DAVEN TO HASHEM FOR ALL THE RIGHT THINGS. WE ARE LIVING IN DIFFICULT TIMES, SO MANY PEOPLE SUFFER AND THERE ARE SO MANY THINGS TO DAVEN FOR.
THIS SHOULD BE A ZECHUS FOR THE NESHAMA OF MOSHE DOVID BEN PINCHUS DOV, HIS NESHAMA SHOULD HAVE AN ALIYA.
