Wednesday Nissan 23, Issru chag 5703, 8th day of the Omer
Chumash: Acharei Mot, Revi'i with Rashi.
Tehillim: 108-112.
Tanya: Now, therefore (p. 223)...the Esoteric Discipline). (p. 225).
The presence of Mashiach is revealed on Acharon Shel Pesach, and this revelation has relevance to all Israel:
Pesach is Medaleg, [1] "skipping over" (rather than orderly progress), and Leil Shimurim, [2] the "protected night."
In general the mood of Pesach is one of liberty.
Then Pesach ends, and we find ourselves tumbling headlong into the outside world. This is where Mashiach's revealed presence comes into play - imbuing us with a powerful resoluteness that enables us to maintain ourselves in the world.
Notes:
Shir HaShirim 2:8. Midrash Raba on that verse describes the Exodus as Medaleg, "skipping over" calculations and rationales for redemption, bringing Israel out of exile regardless of their merit, regardless of the length of the exile. Later in that section the Midrash applies the verse to Mashiach.
Sh'mot 12:42, as Rashi notes, the night destined for redemption.
