Likutei Moharan 19:5/ליקוטי מוהר"ן י״ט:ה׳

15. And this is the concept of the “chance nocturnal emission” (Deuteronomy 23:11). The storm-wind/the spirit of folly/the seventy tongues ascend via Targum / tardemah /sleep and draw from the Holy Tongue/the Holy Spirit/the Holy Covenant.

2For whoever possesses perfection of the Holy Tongue can cool his burning desire through the Holy Tongue, as in (Psalms 39:4), “My heart burned within me… I spoke with my tongue.” He can cool his burning desire with the words of the Holy Tongue, as in (Genesis 2:23), “Now this is bone from my bones.” From here we see that with [the creation of] Chavah, his mind was calmed (Yevamot 63a).

3But when someone lacks perfection of the Holy Tongue, the storm-wind is m’KaRer (cools) him with a “nocturnal miKReh” (chance emission) during sleep. This corresponds to (Deuteronomy 25:18), “When KaRkha (they chanced to meet you) on the way,” which is an aspect of KRirut (a cooling off). “On the way” corresponds to (Proverbs 30:20), “Such is the way of a promiscuous woman.” The storm-wind—by way of the Targum, which is synonymous with the <evil force> of nogah —draws from the above mentioned chashmal, <as is known>.

4Thus Elisha, by inheriting the Holy Spirit from Eliyahu, received from him the perfection of the Holy Tongue. This is alluded to in (2 Kings 2:9), “Let there be a twofold portion of your spirit upon me.” “Twofold” corresponds to the Holy Tongue, as in [the halakhic requirement to read] “the verse twice and the Targum once” (Berakhot 8a). Because of this it is written of him (2 Kings 4:9), “A holy man passes by here all the time.” [Our Sages see this verse alluding to the fact that] “seminal discharge was never seen on his sheet” (ibid. 10b). This is because perfection of the Holy Tongue safeguards a person from nocturnal emission, for through the perfection of the Holy Tongue one merits to rectifying the Covenant, as explained above.

5The reason for this is that the primary perfection of the Holy Tongue is by means of Targum / tardemah and sleep—that is, by refining the concept of Targum / tardemah. Through this one is then saved from the nocturnal emissions of deep sleep, as above.

6{“As for the head of those who surround me, let the mischief of their own tongues cover them. Let fiery coals descend upon them; may it ca st them down into the fire” (Psalms 140:10, 11).} And this is what David requested, “As for the head of those who surround me, let the mischief of their own tongues cover them.” “The head of those who surround me” corresponds to (Ezekiel 1:4), “Nogah surrounding it”—for it [the evil force of the nogah] is the head of those that surround holiness. “Let the mischief of their own tongues cover them,” <in other words,> their mischief and evil should be nullified.

7And regarding the other tongues of the nations—the concept of the “conflagration of the seventy stars”—<he asked>, “Let fiery coals descend upon them; <may it cast them down into the fire>.” This is because “they emanated from fire and fire will consume them” (ibid. 15:7).

8In other words, the concept of nogah / Targum needs to be refined, so that the evil in it will fall away and the good in it will be extracted and ascend. It is then encompassed within holiness, namely, the Holy Tongue. For this is the concept of the perfection of the Holy Tongue through the tongue of Targum, explained earlier. As for the other tongues of the nations, the concept of complete evil, they must be utterly destroyed, as in, “Let fiery coals descend upon them….”

9This is the concept of the flame of fire that descends on Shabbat eve upon the heads of the evil forces. This prevents them from being encompassed in the nogah to draw sustenance from the holiness, <as is known>.

10The meaning of this is as follows: On Shabbat eve, right as Shabbat begins, nogah becomes encompassed in holiness. When this happens, the other forces of evil, the totally impure ones, also seek to ascend to holiness. But then a fiery flame descends upon their heads causing them to fall below. This is the deeper intention behind washing oneself with hot water on the eve of Shabbat, as explained in the Kavanot. It is also the above mentioned concept of having to extract the good in the Targum / nogah, so that it will be encompassed within the Holy Tongue. As for the other tongues of the gentiles, which are complete evil, we have to vanquish and nullify them totally, as has been explained.
