68. The phrase "to one place" IS CALLED YESOD BECAUSE there is a connection to the union of the upper world through YESOD. THE VERSE: "Hashem shall be one, and His Name One" (Zecharyah 14:9) hints at two unions. One is the upper world that is unified in its own grades, WHICH IS THE SECRET OF: "HASHEM IS ONE" and THE SECOND is the lower world that is unified in its own grades, ACCORDING TO THE SECRET: "AND HIS NAME ONE." The unification of the upper world BY THE SECRET OF "HASHEM IS ONE" is up TO YESOD. The life of the worlds, WHICH IS YESOD, is sweetened IN BINAH, and the upper world is connected to its unification. Because of this, it is called: "to one place," as all the grades and all the parts, gather there. And they become as one in it, without any separation at all. No grade unites there wholly save this grade, in which all the lights are mysteriously covered in one desire. Up to this point, REFERRING TO THE WORDS: "AND LET THE DRY LAND APPEAR," the revealed world - WHICH IS THE SECRET OF RACHEL - is unified with the concealed world - WHICH IS LEAH.

373. Rabbi Elazar continued: The first letter, which was floating over the pure knot, was crowned from below and above. It goes up and comes down, SO THAT NOW THE RIGHT IS STRONGER, AND NOW THE LEFT COLUMN. After the waters, WHICH ARE THE MOCHIN, are engraved into their shapes and THE MOCHIN settle in place, THE TWO COLUMNS are included one within the other, AND THIS IS THE SECRET OF THE CENTRAL COLUMN. So all the letters ROSE UP TO ABA AND IMA, AND FIRST RECEIVED THE MOCHIN OF THE RIGHT AND LEFT COLUMNS. THEN, THEY RECEIVED THE MOCHIN OF THE CENTRAL COLUMN, were combined with one another, and crowned by one another until a building OF THE PARTZUF OF ZEIR ANPIN AND HIS FEMALE PRINCIPLE and its Yesod was built upon them.
