207 on the right, 103 on the left
The young man from the previous section continues by explaining that the first Light is combined with the 207 worlds hidden on the right under Binah. There are also 103 worlds on the left side, adding to 310 worlds that God prepares constantly for the righteous. The Light of the right is Chesed, and it produces offspring for every single day, otherwise the world would not be able to exist. It is written, "For I have said, the world is built by love."
The Sfirah of Chesed correlates to the Right Column attribute of mercy, which tempers and sweetens judgment. If our world were balanced towards the Left (Judgment). it would be immediately destroyed. Thus, out of Love for his Creation, God injected mercy (Chesed) into the cosmos, which gives a man time to repent and change his ways before judgments can be executed. In this moment, we rouse the forces of mercy, using it to atone for our sins, complete our spiritual path, and cause unceasing fulfillment to fill all existence.
738. This light is combined with the 207 worlds, which are hidden under that light, and it spreads in all of them. Below the concealed supernal Throne, WHICH IS BINAH, these 207 worlds dwell at that right side. There are 310, 207 on the right side and 103 from the left side, and together they equal 310. They are the ones that the Holy One, blessed be He, prepares constantly for the righteous, and from these spread many, many treasures of delight. They are all hidden for the righteous to delight with in the World to Come. Of this, it is written, "That I may cause those who love me to inherit substance (Heb. yesh, Yud-Shin); and I will fill their treasures" (Mishlei 8:21). About all these, it is written, "Neither has the eye seen, (that) an Elohim beside You... " (Yeshayah 64:3).
738. אוֹר דָּא אִתְכְּלִיל בְּמָאתָן וְשִׁבְעָה עָלְמִין, דְּאִינּוּן גְּנִיזִין בְּסִטְרָא דְּהַהוּא אוֹר, וְאִתְפָּשַּׁט בְּכֻלְּהוּ. תְּחוֹת כּוּרְסְיָיא עִלָּאָה טְמִירָא, שַׁרְיָין אִינּוּן עוֹלָמוֹת, מִסִּטְרָא דְּהַהוּא יְמִינָא. תְּלַת מֵאָה וָעֶשֶׁר אִינּוּן, מָאתָן וְשֶׁבַע, אִינּוּן בְּסִטְרָא דִּימִינָא. מֵאָה וּתְלַת, אִינּוּן בְּסִטְרָא דִּשְׂמָאלָא. וְאִינּוּן תְּלַת מֵאָה וָעֶשֶׁר. וְאִלֵּין אִינּוּן דְּקוּדְשָׁא בְּרִיךְ הוּא מְתַקֵּן תָּדִיר לְצַדִּיקַיָּא, וּמֵאִלֵּין מִתְפַּשְּׁטָן כַּמָה וְכַמָּה אוֹצְרֵי חֶמְדָּה, וְכֻלְּהוּ גְּנִיזִין לְאִתְעַדְנָא מִנְהוֹן צַדִּיקַיָּא לְעָלְמָא דְּאָתֵי וְעַל אִלֵּין כְּתִיב לְהַנְּחִיל אוֹהֲבַי יֵשׁ וְאוֹצְרוֹתֵיהֶם אֲמַלֵּא וְעַל אִלֵּין כְּתִיב עַיִן לֹא רָאָתָה אֱלֹהִים זוּלָתְךָ וְגוֹ.'
739. Yud-Shin (310) are the 310 worlds that are concealed under the World to Come, NAMELY UNDER BINAH. These 207 worlds, which are on the Right Side, are called ‘First Light’, because even the Light of the Left is called ‘light.’ IT IS A DIM LIGHT THAT PRODUCES NO OFFSPRING. SINCE THE LIGHT OF THE RIGHT, WHICH IS CHESED, PRECEDES THE LIGHT OF THE LEFT. But the First Light will produce offspring in the World to Come. And if you say that this is true only for the World to Come, WHICH IS BINAH, and no more, yet it produces offspring every single day, MEANING EVEN FOR THE LEVELS OF ZEIR ANPIN THAT IS CALLED ‘DAY.’ For if this light would not be IN ZEIR ANPIN, then the world, WHICH IS MALCHUT, would not be able to exist, as it is written, “For I have said, the world is built by love (chesed)” (Tehilim 89:3), MEANING WITH THE FIRST LIGHT THAT IS CALLED ‘CHESED.’
