14 Adar: Unlimited Joy
UNLIMITED JOY
All festivals will become insignificant in the future, except for Purim, as the Book of Esther (9:) states, “These days of Purim shall never cease to be celebrated....”
(Medrash Mishlei 9:2; Yalkut Shimoni, Mishlei, sec. 944)
The joy of the festivals is limited and will be overshadowed by the infinite joy of Moshiach. Only the festival of Purim will remain significant in the time of Moshiach. Since it is a festival of unlimited joy, it is a taste of Moshiach.
Sichos Acharon shel Pesach 5717, sec. 10.
