Likutei Moharan 78:2/ליקוטי מוהר"ן ע״ח:ב׳

12. This is the exile of the Shekhinah—that the power of speech, which is the Shekhinah, is in exile and is struck dumb, as it is written (Psalms 39:3), “I was dumb with silence.” This is the meaning of “Have you indeed been struck dumb when you ought to be speaking justice?” (ibid. 58:2). Justice is Malkhut of Holiness (Tikkuney Zohar, Introduction, p.17b), as is known. And Malkhut, as explained above, is speech. When it is in exile, it is struck dumb.

2{“Take words with you and return to God” (Hosea 14:3).} <Said differently,> he must effect rectification through the very means by which he caused blemish—namely, words of confession, as Scripture states: “Take words with you.” He should confess constantly, with sincerity, “in the presence of God” (Lamentations 2:19), and so “return to God.” Whatever speech he blemished will thus return to its source. This is the concept of the unification of the Blessed Holy One and His Shekhinah, for he unites speech, which corresponds to the Shekhinah, with God.

3This is also stated by the verse (Isaiah 40:5): “Then the glory of God will be revealed, and all flesh will see it together; for the mouth of God has spoken.” That is, when he unites speech with God—which is the unification of the Blessed Holy One and His Shekhinah—then “the glory of God will be revealed.” “The glory <of God>” is the Shekhinah, <as explained elsewhere>. <This is so that the illumination of the Divine persona Malkhut will be revealed.>

4Presently, Her Light is diminished and Her power weakened, as it is written in the Holy Zohar: The Shekhinah screams, “Sustain me with dainties… for I am love-sick” (Song of Songs 2:5). This refers to Her love for Israel: I dwell with them, even in the midst of their impurity. This is the Shekhinah in exile. But <when one> unites speech—which corresponds to Malkhut and the Shekhinah—with God, the Light of the Divine persona Malkhut is revealed and enhanced. This is the meaning of “In the light of the King’s countenance there is life” (Proverbs 16:15). That is, <by rectifying the Light of> the Divine persona Malkhut he can live, because he draws life from the attribute of Malkhut, which is his source, as explained above.
