Rav Yitzchok Hutner wonders how we are allowed to experience complete and unbridled simcha on Purim, seeing as the Gemara in Brachos comments that it is forbidden for one to do so in this world - and that we are mandated to always temper our happiness with feelings of awe. He answers that Purim is not part of this present world; rather it is intended as an other-worldly experience that is meant to give us a taste of what the future Messianic times will be like.
In this unique work, readers will better understand - and experience - the eternal joy of Purim.
