Likutei Moharan 49:5/ליקוטי מוהר"ן מ״ט:ה׳

15. This is the aspect of the song that will be roused in the Future. It is a simple-twofold-threefold-fourfold song, this being the Ten Kinds of Song.

2This is the heh, which is a dalet and a yod. The dalet is the aspect of a simple-twofold-threefold-fourfold song; the yod is the aspect of the Ten Kinds of Song.

3This <comes about> through the revelation of His Kingship, in the aspect of “sarah (she ruled) over the entire world.” And SaRah is the aspect of ShiR (song), corresponding to “Then the ShaRim (singers) will be like flute players.” This is also the aspect of the kingdom of David, for he is “the sweet singer of Israel” (2 Samuel 23:1).

4This is the explanation of: If your wife is short, bend down and l’ chish (listen) [to her] (Bava Metzia 59a). Rashi comments: listen to her counsel.

5In fact, a Godfearing woman is the aspect of advice. When the prayer—i.e., the aspect of <David’s> kingdom—is lowly and KaTNut (constricted)—in the aspect of “your wife is short,” and “we have a KTaNa (little) sister” (Song of Songs 8:8) —it corresponds to “the KaTaN (lesser) light” (Genesis 1:16), in the aspect of “his counsel falls away” (Sanhedrin 22a).

6[When prayer is lowly] it is necessary to erect it, in the aspect of “I will erect the <fallen> sukkah (booth) of David” (Amos 9:11). SuKkah is SaRah, for “she SaKhtah (foresaw) with the spirit of holiness” (Megillah 14a), and Sarah is Malkhut. [Prayer is also] the aspect of “the counsel of God that will stand” (Proverbs 19:19), and the aspect of “the two great lights” (Genesis 1:16).

7This is “L’ChiSh (listen) to her” <and> accept her counsel—<the aspect of> the ascent of the prayer, which is [recited] b’LaChaSh (silently), for it is the service of the heart.
