Here we learn that the sanctuary is the highest place, Chochmah, and that Malchut receives blessings from God through the Righteous. The righteous man, because he is deserving, increases peace above and below, as do the words of Torah.
204. "Lift up your hands in the sanctuary" (Tehilim 134:2): HE ASKS, What is the sanctuary? HE SAYS, IT IS the highest place, CHOCHMAH, whence the source of the deep river, BINAH, comes from, as written, "And a river went out of Eden to water" (Beresheet 2:10), THE RIVER BEING BINAH and Eden the name of the highest sanctuary. Hence, "lift up your hands in the sanctuary;" NAMELY, ONE SHOULD RAISE HIS HANDS TO CHOCHMAH AND RECEIVE THEREFROM HOLINESS IN ABUNDANCE. A man who does so and attains it, they proclaim of him: "May Hashem...bless you out of Zion" (Ibid. 3). NAMELY, you shall bless the Holy One, blessed be He, out of the place called the supernal sanctuary, and He will bless you out of the place called Zion, so that you and the Queen shall be blessed together.
205. As your union OF THAT MAN AND MALCHUT is made in order to praise the King, the Congregation of Yisrael is also blessed out of that place, NAMELY OUT OF ZION, WHICH IS HER YESOD, out of which place He will call forth blessings on you. Hence, it says, "Hashem shall bless you out of Zion: and you shall see the good of Jerusalem" (Tehilim 128:5). What is the good of Jerusalem? These are the blessings that come to MALCHUT from the King through the holy grade of the Righteous, NAMELY YESOD OF ZEIR ANPIN. Of this, Scripture says, "Hashem shall bless you out of Zion: and you shall see the good of Jerusalem." It is all the same.
206. "And you shall see your children's children..." (Ibid. 6). HE ASKS, "And you shall see your children's children" is very well. What though is this latter phrase in the verse: "And peace on Yisrael?" What does "on Yisrael" imply here? HE ANSWERS, Since THAT MAN increases peace above because he is so deserving, he increases peace above and below, peace on Yisrael - NAMELY, YISRAEL BELOW - and peace, which is the praise of the upper and lower, the praise of all the worlds. Words of Torah increase peace in the world, as written, "Hashem will give strength to His people; Hashem will bless His people with peace" (Tehilim 29:11).
