1. "And Hashem spoke to Moses, saying, 'Speak to Aaron, and say to him: When you kindle the lamps...'" (Bemidbar 8:1-2). Rabbi Yehuda opened the discussion saying, "which is like a bridegroom coming out of his chamber..." (Tehilim 19:6). Praised is the lot of Yisrael that the Holy One, blessed be He, favored them and granted them the Torah of Truth, a Tree of Life by which a person inherits life for this world and life for the World to Come. Whoever tries to learn Torah and holds to her has life. Whoever leaves the words of the Torah and separates from the Torah is as if he took leave of life, since she is life and all her words are life, as it is written, "for they are life..." (Mishlei 4:22), and, "I shall be health to your navel..." (Ibid. 3:8).
2. Come and behold: the Tree of Life, WHICH IS ZEIR ANPIN, is attached from above downwards. The light of this sun, WHICH IS ZEIR ANPIN, that shines upon all, begins from the top, THAT IS, CHOCHMAH, BINAH AND DA'AT, and spreads to the trunk of the tree, WHICH IS TIFERET, in a straight path. Two sides are attached to it, one to the north and one to the south, one right, WHICH IS CHESED, and one left, WHICH IS GVURAH. When the sun illuminates from the trunk of the tree, as we have learned, it FIRST strengthens the right arm, WHICH IS CHESED, and shines with force. From that force OF THE RIGHT, the left illuminates, WHICH IS GVURAH, and is included in its light.
3. "Which is like a bridegroom coming out of his chamber." HE ASKS: What is his chamber? HE RESPONDS: That is "the crown with which his mother crowned him on the day of his wedding" (Shir Hashirim 3:11). THESE ARE THE MOCHIN - CHOCHMAH, BINAH AND DA'AT - THAT HE RECEIVED FROM HIS MOTHER, WHO IS BINAH. "...Coming out of his chamber..." that is the top of all the light, MEANING CHOCHMAH, BINAH AND DA'AT, as you say in the following scripture: "His going forth is from the end of the heaven" (Tehilim 19:7). This is the beginning of everything that is referred to as 'the end of the heaven,' MEANING BINAH, FROM WHICH EMERGES AND BEGINS ZEIR ANPIN, REFERRED TO AS 'HEAVENS.' Then he emerges. Like a real bridegroom when he goes out to meet his soul beloved bride, he stretches out his arms, WHICH ARE CHESED AND GVURAH, and receives her.
4. Similar is the verse, "which is like a bridegroom coming out of his chamber." The sun, ZEIR ANPIN, continues to spread to the west, WHICH IS MALCHUT. As soon as the west gets nearer, the north side is the first to be aroused toward it, THAT IS GVURAH, and approaches to the west. It joins it at that place. As we have learned, THE BEGINNING OF ZEIR ANPIN COUPLING IS ON THE LEFT, WHICH IS GVURAH. THAT IS THE SECRET OF RECONCILIATION AND GETTING PERMISSION, as it is written: "His left hand is under my head" (Shir Hashirim 2:6). Following that is the south side, which is right, MEANING CHESED, as it is written: "And His right hand embraces me" (Ibid.). Then it "rejoices like a strong man to run a race" (Tehilim 19:6), to illuminate the moon FROM THE CENTRAL COLUMN, THAT IS YESOD. And this has been explained. Come and behold: "when you kindle the lamps;" these are the loftiest candles, WHICH ARE THE SFIROT OF MALCHUT, which all shine brightly in unison from the sun, WHICH IS ZEIR ANPIN.
