"The King's strength also loves judgment"
Rabbi Yosi explains that the title verse refers to God and the power by which He strengthened the realm of Malchut. This power was derived through judgment. Malchut, and therefore the Congregation of Yisrael, was established through judgment - that is, the Mochin that includes Chochmah and Chassadim together.
Spiritual balance between mercy and judgment is created within our souls and the world around us by virtue of the spiritual energy bottled up within the mystical words of this ancient text. Balance is critical if we are to live a life of fulfillment. For instance, if the scales are tipped towards the side of judgment, we'll find the world extra hard on us. The objective of this passage is to balance our ability to extend mercy and judgment to others so that we receive the same compassionate blend of judgment and mercy from the world.
476. Rabbi Yosi opened the discussion saying, "The King's strength also loves judgment (or: 'justice'). You do establish equity" (Tehilim 99:4). "The King's strength also loves justice" refers to the Holy One, blessed be He, NAMELY THE NUKVA WHO LOVES JUSTICE, WHICH IS MOCHIN INCLUDED OF RIGHT AND LEFT TOGETHER. "The King's strength" is the power with which the Holy One, blessed be He, strengthened THE NUKVA, which comes only through justice, as it is written, "The King by justice establishes the land" (Mishlei 29:4) BY BEING INCLUDED OF CHOCHMAH AND CHASSADIM TOGETHER, CHASSADIM ON THE RIGHT AND CHOCHMAH ON THE LEFT.
476. פְּתַח רִבִּי יוֹסֵי וַאֲמַר, וְעֹז מֶלֶךְ מִשְׁפָּט אָהֵב אַתָּה כּוֹנַנְתָּ מֵישָׁרִים וגו,' וְעֹז מֶלֶךְ מִשְׁפַּט אָהֵב, דָּא קוּדְשָׁא בְּרִיךְ הוּא. וְעֹז מֶלֶךְ: תּוֹקְפָא דְּאַתְקֵף קוּדְשָׁא בְּרִיךְ הוּא, לָאו אִיהוּ אֶלָּא בְּמִשְׁפָּט, דְּהָא בְּמִשְׁפָּט אִתְקַיַּים אַרְעָא, כְּד"א מֶלֶךְ בְּמִשְׁפָּט יַעֲמִיד אָרֶץ.
477. This is the reason SCRIPTURE SAYS, "The King's strength also loves justice," for the Congregation of Yisrael, THE NUKVA, is not established save through justice, WHICH IS MOCHIN INCLUDED OF CHOCHMAH AND CHASSADIM TOGETHER. Since it is fed thereof, THE SECRET OF CHASSADIM and all the blessings it receives are from there, THE SECRET OF CHOCHMAH. Therefore, "the King's strength also loves justice," for all it desires and craves is to receive justice. "You do establish equity (lit. 'equities')" is the secret of the two Cherubs below CALLED EQUITIES, who rectify and render the world inhabited.
477. וּבְגִין כָּךְ, וְעֹז מֶלֶךְ מִשְׁפָּט אָהֵב, וְלָא אִתְתַּקָּנַת כְּנֶסֶת יִשְׂרָאֵל אֶלָא בְּמִשְׁפָּט, בְּגִין דְּמִתַּמָּן אִתְּזָנַת, וְכָל בִּרְכָאן דְּנָטְלָא, מִתַּמָּן נָטְלָא. וּבְגִין כָּךְ וְעֹז מֶלֶךְ מִשְׁפָּט אָהֵב, כָּל תְּאִיבוּ, וְכָל רְחִימוּ דִילָהּ לָקֳבֵיל מִשְׁפָּט. אַתָּה כּוֹנַנְתָּ מֵשָׁרִים, רָזָא דִתְרֵין כְּרוּבִים לְתַתָּא, דְּאִינוּן תִּקּוּנָא וְיִישׁוּבָא דְעַלְמָא, וְהָא אִתְּמָר.
