Consistent with the theme that runs through almost all the Sichos of Dvar Malchus, the Rebbe address in this Sicha the split between Above and Below, “Oneness” and multiplicity. Paraphrasing the Mishna in Pirkei Avos: the dimension of “one utterance” and that of “ten utterences”.
The aspect of “one utterance” (through which the world could have been created) refers to the higher dimension, where the simple Oneness of G-dliness is the only reality, and any created entity is completely nullified to that Oneness, losing all individual importance.
The aspect of “ten utterences” (through which the world was created) refers to the lower reality where every entity has it’s own role and unique importance distinct from the greater unity and Oneness. This dimension of reality, however, can impose upon — and even conceal — the Oneness that underlies and permeates Creation.
In other words, “one utterance” brings a complete nullification of the world, whereas the “ten utterences” are what generate the reality of world (although in a way where the world is permeated with Holiness drawn down from Above).
The “problem” here is that each one cancels out the other, which is not the Divine intent. Says the Rebbe:
..the true perfection is the combination of the two together — that also the level of G-dliness that is above the world (“one utterance”) is drawn down and revealed and permeates the multiplicity of the individual created begins (“ten utterences”). Through this the intent of Creation is fulfilled, that the Holy One desired a dwelling place in the lower realms.
What is the true definition of the famous expression דירה בתחתונים (a “dwelling place in the lower realms”)? It is the unification of the Upper and Lower dimensions. Not in a way that the Higher dimension (עליונים) descends from it’s lofty level, for then it is no longer truly Higher; and not in a way where the Lower ascends from it’s own level, for then it is no longer truly Lower. Rather: “The Upper as it is in its loftiness becomes united with the Lower as it is in its lowliness…”
In other words, Torah and G-dliness remain lofty (not sacrificing their inherent loftiness and Holiness in order to fit into the limitations of the earthly perspective); man remains earthly (physically eating, drinking, sleeping, etc.) — but these same “earthly” matters of the man down below become permeated with the loftiest dimensions of Above. When we achieve this, we have created a dwelling place (for Hashem’s essence, His “true self”, so to speak) in the lower realms (which remain earthly and lowly).
This is the purpose of the Giving of the Torah. But the Torah cannot only be “given” by Hashem, it must also be “received” by us. In order to become a proper vessel to receive the Torah (especially that level of Torah which is above the world and man) a person must leave his reality through complete self-nullification (תכלית הביטול). This self nullification will express itself through the impossibility of machloikes, since the reason for machloikes is one’s ישות lack of self-nullification. In this way one becomes fitting and prepared to receive the level of the Torah that is above any connection to the world, which is the level of Torah that will be revealed in the true and complete Geulah.
That is the preparation to receive this level of the Torah; but to actually receive it means that through learning with understanding and comprehension it will permeate and become the person’s reality. And through this:
Immediately we will see that Moshiach is already found among us, and every single Jew will point with his finger and say “Behold, this one (is the Melech haMoshiach, and he already) came”.
