May we have unbounded rejoicing, reaching the level where we "do not know the difference between 'Cursed be Haman' and 'Blessed be Mordechai.'"

This will occur to the fullest in the Messianic age, when all the undesirable elements associated with "Cursed be Haman" will be transformed through our service into "Blessed be Mordechai."(The Rebbe)
(L'Chaim)
