Towards the end of the sicha of parshas Mishpotim, the Rebbe elucidates on the meaning of the monthly dates of 25, 26, 27, 28, and erev Rosh Chodesh.  We can see how the Rebbe is in fact laying out a roadmap for the avoidah of Chassidim after 27 Adar (the medical event that occurred to the Rebbe one month after this sicha, which affected the Rebbe’s speech, etc.): 

• 25th (כה) and 26th (כו) refer to Birkas Cohanim, giving Divine blessing (ונתינת כח) to the Yidden in the time of golus and also in the Beis Hamikdosh, when Hashem (gematria 26) is “before them” (hinting at having Hashem’s shliach, Nosi Doreinu, in front of us at the time the Sicha was said);
• 27th (ז”ך) is associated with the verse “shemen zayis zach (ז”ך)”, which serves as the basis of the maamor the “V’Atah Tetzaveh”, which would be distributed by the Rebbe for Purim Koton.  This can be read as a hint at the avoidah in that maamor (being crushed from being in Golus, even when there is spiritual and material abundance) — the “crushing” that would begin on the 27th of the following month of Adar;
• 28th (כח) is not only “adding strength”, but is also the gematria of “Yechi”, the declaration of Chassidim which took root after 27 Adar (with the repeated encouragement of the Rebbe);
• 29th is erev Rosh Chodesh, the time of concealment (hinting at Gimmel Tammuz and thereafter) which precedes Rosh Chodesh (which refers to Geuloh).  In the  maamor of Beis Iyar the Rebbe explains how the concealment of the moon is actually the preparation for the unification of the Mashpia and the Mekabel on Rosh Chodesh, and in the maamor of Rosh Chodesh Kislev the Rebbe addresses the great level of the avoidah of the tachton at the time of concealment.

A roadmap of the avoidah from before and after 27 Adar, through Gimmel Tammuz, up to today: the giving of the power to succeed (25th, 26th);   the “crushing” that brings out the essence (27th); the declaration of Yechi (28th); until the complete concealment of erev Rosh Chodesh that brings about the highest avoidah and leads to the true redemption.

Although the trip has been longer than anyone expected, we have received clear directions, and know that the road leads to the true and complete Geuloh, so “step on it”!
