Now, drawing down Hashem’s Chochma-Wisdom Above into physical matters is by way of the light of Kesser-Crown. וְהִּנ ֵה הַמְש ָכַת חָכְמָה עֶלְיוֹנָה ב ִּדְ בָרִּ ים ג ַ םיִּ יִּמְ ש , הו א עַל יְדֵי אוֹר הַכ ֶתֶר .
The Mittler Rebbe explains in Toras Chaim: The Alter Rebbe’s question was: If the Lofty Wisdom of Hashem Above is too exalted to be perceived by any creation, then how did it descend into the Torah we have down here and in physical mitzvos? What caused this Lofty Wisdom to clothe itself in its external dimension to be able to descend into our world?
The Alter Rebbe’s answer is that there is a power even higher than the Lofty Wisdom, that causes it to descend (through its external dimension). This higher power is the level of Keser-Crown. Just as a crown is above the head, so too, this transcendent level of Kesser which is higher than Atzilus enables the Wisdom of Atzilus to descend to our world.
For, even though “The Torah is derived from Chochma” (Zohar II 121a), this is only on a revealed level, but its true source is above even the level of Chochma. כ ִּי "אוֹרַ יְיתָא מֵחָכְמָה נָפְקָ ת" – ב ִּבְחִּינַת ג ִּיל ו י, אֲבָל מְ קוֹרָה הו א לְמַעְלָה ;
For, the 613 mitzvos of the Torah and the 7 Rabbinic mitzvos form the 620 Pillars of Light. ש ֶת ַרְ יַ"ג מִּ צְוֹת ד ְ אוֹרַ יְיתָא וְז' ד ְ רַ ב ָנָן הֵם "תר"ך עַמ ו דֵי אוֹר" .
The number “תר"ך-620” is the numerical value of the word “כ ֶתֶר-Crown,” and the same letters in a different order. Thus, the Mitzvos, which total 620 (including the Rabbinic Mitzvos) are directly connected to “Kesser-Crown,” the level that transcends Atzilus.
This source of the Mitzvos is referred to in the Zohar (III 129a) as “The White Paths of the Gulgalta,” וְהו א מֵ"אָרְ חִּין לַבְנו נִּית ד ְ גֻלְג ַלְת ָא" ,
(זֹהַר חֵלֶק ב קכ .א ,או רְ אֵ ה ש ָ ם פה, א). (פ ַרְ ד ֵ ס ש ַעַ ר ח פ ֶרֶ ק ג .) (רְ אֵ ה זֹהַר חֵלֶק ג קכ .)א ,ט
