Thos sicha was said on Shabbos Vayeitze, which corresponded in 5752 to the 9th of Kislev, the birthday and hillula (day of passing) of the Mitteler Rebbe, the 2nd Rebbe of Chabad.
The Alter Rebbe, his father, represented the attribute of Chochma (wisdom), and his son the Mitteler Rebbe represents the attribute of Bina (understanding). Just as Bina expands and reveals the breadth and depth of Chochma, so, too, the teachings of the Mitteler Rebbe are “wide as a river”, allowing one to drink deeply from the wellsprings of pnimiyus haTorah. This is significant to bringing the Geuloh, because:
At this time there needs to be…the study of pnimiyus Hatorah as it has been revealed in the teachings of Chassidus, and the fulfillment of the instructions of our Rebbeim. This includes — learning the subjects of Moshiach and Geuloh, in a way that it opens the heart and the eyes and the ears — so that they will understand, and see and feel the true and complete Geuloh tangibly in the physicality of the world.
Not merely learning as some sort of intellectual exercise, but rather “in a way of seeing, that this [the true and complete Geuloh] is already prepared and ready, and one only needs to open the eyes and then he will see this!“
Practically speaking, this means adding in the learning of the Torah of the Mitteler Rebbe, for his teachings are specifically in a way of Bina. It is through learning in a way of Bina, understanding, where it becomes integrated with a person, that the studies have an effect on the person. This means an effort to express his “spirituality” and his chassidishkeit in his physical matters, until there will be no divide between his “spiritual” aspect and his physical being.
Furthermore, this can impact the world dramatically, because:
We have completed all the birurim (refinement), including the refinement of “Esav he is Edom”, and how much more so considering that even in the time of Yaakov Avinu he already thought that Esav was refined (and from Yaakov’s level in fact he was). And all the more so after all of the avodah that has taken place since then (to refine Esav) until we are at the point where Esav is already completely refined, as we see in the conduct in our days (golus Edom) of the nations of the world who are related to “Esav he is Edom”, such as this country, a country of kindness, and such conduct is spreading to other nations, as we see lately.
We find that Yidden are ready, the world is ready, even the nations of Esav are ready. What remains, then, to be done?
The only thing lacking is — that a Jew should open his eyes properly, and should see how everything is ready for the Geuloh! There is the “set table” already, and there is already the Leviyoson and the Shor Habor and the aged wine, and Yidden are sitting at the table — “their father’s table”, together with Moshiach Tzidkeinu (as stated in seforim that in every generation there is one of the seed of Dovid who, due to his righteousness, is fitting to be Moshiach), and there is already a “heart to know and eyes to see and ears to hear”.
Let us open up the seforim and open up our eyes and ears and hearts to know the truth of the only one who is fitting to be the redeemer, and in that way we empower him (as the Rebbe said in the sicha of Chayei Sara) to redeem the Jewish nation from golus!
