Hebrew translation:

271. אִי חָסִיד קָדוֹשׁ, כַּמָּה מְשַׁבֵּחַ רֹאשׁ הַיְשִׁיבָה הֵיכָל אֶחָד שֶׁהוּא בְּרֹאשׁ צַד מִזְרַח הָעֲזָרָה הַזּוֹ, מִשּׁוּם שֶׁאַרְבָּעָה הֵם בְּאַרְבַּעַת צִדְדֵי הָעוֹלָם. אֲבָל הֵיכָל שֶׁל צַד מִזְרָח מַרְבֶּה אוֹרוֹתָיו יוֹתֵר מִכֻּלָּם.
272. יוֹם אֶחָד בַּיָּם הַגָּדוֹל יָצָא לִוְיָתָן, וְכָל הַיָּם הִזְדַּעֲזַע, וְכָל הַדָּגִים הָלְכוּ לְכָאן וּלְכָאן. כְּשֶׁהִגִּיעַ הַלִּוְיָתָן לְפֶתַח פֶּתַח הַתְּהוֹם, מַתְחִיל לִשְׂמֹחַ, וְשָׁכַךְ שָׁם הַתְּהוֹם, אֶלָּא אוֹתוֹ כְּמַרְאֵה הַמַּעְיָן, וּמִתְכַּסִּים הָאוֹרוֹת, וְלֹא נִרְאוּ כָּל אוֹתָם אוֹרוֹת, פְּרָט לְאוֹר הַהֵיכָל שֶׁבְּצַד הַמִּזְרָח הַזֶּה.
273. אוֹתָהּ מַרְגָּלִית שֶׁמּוֹצִיא הַלִּוְיָתָן מִתּוֹךְ אוֹתוֹ תְהוֹם שֶׁנִּקְרָא סַגְדּוֹ”ן, מִמַּה נֶּעֶשְׂתָה? אֶלָּא יוֹם זֶה שֶׁמּוֹצִיא הַלִּוְיָתָן שֶׁהִזְדַּעֲזַע הַיָּם, יוֹם שֶׁנֶּחֱרַב בֵּית הַמִּקְדָּשׁ, הוּא ט’ בְּאָב. וְאוֹתָהּ מַרְגָּלִית, שֶׁכְּשֶׁזּוֹכֵר הַקָּדוֹשׁ בָּרוּךְ הוּא אֶת בָּנָיו וְזוֹרֵק שְׁתֵּי דְמָעוֹת לְתוֹךְ הַיָּם הַגָּדוֹל, אַחַת נוֹפֶלֶת לְתוֹךְ תְּהוֹם זֶה שֶׁנִּקְרָא סַגְדּוֹ”ן, וְאַחַת נוֹפֶלֶת לְתוֹךְ תְּהוֹם אַחֵר שֶׁנִּקְרָא גִּילְבָ”א.


Zohar Shelach Lecha
Continued from previous DZ
The head of the Yeshiva praises one of the halls on the east side of the Azara because there are four aspects to the Azara, to the four directions, which are South that is Chessed, North for Gevura, East for Tiferet, and West for Malchut. The hall on the east side illuminates its lights more than all the others.

One day, a Leviathan (whale) comes out in the great sea, and the whole sea shakes, and all the fish scatter in different directions. When the Leviathan reaches the opening of the abyss, he begins to rejoice, and the deep becomes still and silent.
(the Zohar has some missing text here)
But there is one like a spring; its lights are covered and not visible, except the lights in the hall on the east side.

The Leviathan takes out a gem from the abyss that is called סַגְדּוֹ”ן. He asks, what is it made of? And he replies, the day that the Leviathan took out the gem, and the sea shook, was when the Holy Temple was destroyed, the ninth day of Av. That gem is made when the Holy One, Blessed be He remembers his children and sheds two tears into the great sea, one tear falls into this abyss, which is called סַגְדּוֹ”ן, and one tear falls into another abyss, which is called גִּילְבָ”א.

The Leviathan is the secret of Yessod of Zeir Anpin and the ‘Sea’ is Malchut. On the ninth of Av, the Holy ne Blessed be He shed two tears (=gems) that falls into Malchut and the Leviathan picks them because they are pure light that the Leviathan would need in the future to fight and kill the Ox to bring about the final unification of the Light with Malchut.
This Zohar section connects to the Talmud: https://www.sefaria.org/Taanit.30b.4?lang=bi
וַחֲכָמִים אוֹמְרִים: כׇּל הָעוֹשֶׂה מְלָאכָה בְּתִשְׁעָה בְּאָב וְאֵינוֹ מִתְאַבֵּל עַל יְרוּשָׁלַיִם — אֵינוֹ רוֹאֶה בְּשִׂמְחָתָהּ, שֶׁנֶּאֱמַר: ״שִׂמְחוּ אֶת יְרוּשָׁלִַים וְגִילוּ בָהּ כׇּל אֹהֲבֶיהָ שִׂישׂוּ אִתָּהּ מָשׂוֹשׂ כׇּל הַמִּתְאַבְּלִים עָלֶיהָ״, מִכָּאן אָמְרוּ: כׇּל הַמִּתְאַבֵּל עַל יְרוּשָׁלַיִם — זוֹכֶה וְרוֹאֶה בְּשִׂמְחָתָהּ, וְשֶׁאֵינוֹ מִתְאַבֵּל עַל יְרוּשָׁלַיִם — אֵינוֹ רוֹאֶה בְּשִׂמְחָתָהּ. תַּנְיָא נָמֵי הָכִי: כׇּל הָאוֹכֵל בָּשָׂר וְשׁוֹתֶה יַיִן בְּתִשְׁעָה בְּאָב — עָלָיו הַכָּתוּב אוֹמֵר: ״וַתְּהִי עֲוֹנוֹתָם עַל עַצְמוֹתָם״.
And the Sages say: Whoever performs labor on the Ninth of Av and does not mourn for Jerusalem will not see her future joy, as it is stated: “Rejoice with Jerusalem and be glad with her, all who love her; rejoice for joy with her, all who mourn for her” (Isaiah 66:10). From here it is stated: Whoever mourns for Jerusalem will merit and see her future joy, and whoever does not mourn for Jerusalem will not see her future joy. This is also taught in a baraita: Whoever eats meat or drinks wine in the meal before the Ninth of Av, about him the verse states: “And whose iniquities are upon their bones, because the terror of the mighty was in the land of the living” (Ezekiel 32:27).

Hashem shed tears on the destruction of his house on the ninth of Av to tell us that he will resurrect it from the ashes and rebuild it himself. We join Hashem with the pain of not having the Holy Temple, so we can rejoice with him when the house takes it proper place in Jerusalem to continue the Light from above.
