Moshiach's Arrival on the 14th of Nissan (Audio, 5:33). The klipa of Amalek - doubting Hashem - is wiped out during the 30 days between Purim and Pesach - 720 hours.
The gematria of Amalek is 240. Since we're working to strengthen faith in Hashem on three levels - thought/word/deed - this equals 3 times 240, which is 720. (Chiddush found in a letter written by Rav Avraham Kokhav-Lev Sternhartz z”l, based on the Bnei Yissa’char).
Throughout these hours Hashem extends a special kindness to rescue every Jewish soul from impurities. This is on condition that the person is careful about their use of time during this period.
Based on Likutey Moharan 2, Torah 74, and Sefer Chessed l'Avraham, by the father of the Chida z"l. Speaker: Rabbi Nasan Maimon.
