Likutei Moharan, Part II 5:9/ליקוטי מוהר"ן·תנינא ה׳:ט׳

19. And this is the concept of a dream mediated by an angel. For these pure words are the concept of an angel, i.e., a dream mediated by an angel. This is because the spoken word is the vestige of the mind. That which is imprinted and concealed in the mind is engraved and imprinted in speech. Thus, when the intellects are refined, so that pure words are made, then even when the conscious mind departs during sleep and the only thing that remains is the mind’s vestige, which is speech, the vestige, too, is refined. This is the concept of a dream mediated by an angel.

2This is the reason that after Moshe’s passing the commander of God’s host came and said: “Now I have come!” (Joshua 5:14). Moshe’s passing signifies the departure of daat, which is analogous to sleep, at which time daat departs and all that remains is the vestige. Therefore, “He said, ‘… I am the commander of God’s host’”—i.e., an angel—“Now I have come!” What remains then is the vestige, the concept of angel—i.e., a dream mediated by an angel.

3And this is the meaning of “The Lord gives the word; the heralds are a great host” (Psalms 68:12). “The Lord gives the word” corresponds to pure words, the vestige of the mind, which is the concept of an angel. Thus this is the meaning of “the heralds are a great host”—i.e., the angels.

4This also relates to what is brought in the writings of the Ari, of blessed memory, that tzevaot is the hidden element of Shadai. As explained there, the “hidden” [letters] of shIN daLeT yOD, with one added for the word itself, has the same numerical value as TZeVAOT. In other words, the hidden element of Shadai signifies the departing of Shadai /intellects during sleep. All that remains is the vestige, Shadai’s hidden element. Therefore, this vestige, being the hidden element of Shadai, corresponds to tzevaot, an angel.

5This is the meaning of “The hair of His head is like clean wool” (Daniel 7:9). “The hair of His head” alludes to the intellects’ shining radiance. This is because the hair emerges from the intellects. When the intellects are clean and refined, then the vestige itself becomes the concept of an angel. This is the meaning of “like clean amar (wool).” AMaR is an acronym for “Oseh Malakhav Ruchot (He makes the winds His angels)” (Psalms 104:4), alluding to the angels created by the vestige when the intellects are clean and refined. However, when the intellects are not clean and refined, the Se’ARot (hairs) become “and Se’IRim (goats) will dance there” (Isaiah 13:21)—the concept of a dream mediated by a demon.

6This corresponds to the human level and the animal level—conceptually, a dream mediated by an angel and a dream mediated by a demon.

7A dream mediated by an angel is synonymous with the human level, as in “Let us make the human in our image, after our likeness” (Genesis 1:26). “After our likeness” refers to the power of imagination, which is “in our image,” the concept of an angel—i.e., a dream mediated by an angel. During sleep the conscious mind departs and the only thing that remains is the power of imagination. Now, when the intellects are refined, the remaining power of imagination, too, is the concept of an angel. This is as in ‘after our likeness, in our image’: the power of imagination is “in our image,” in the concept of an angel—i.e., a dream mediated by an angel. This corresponds to the human level, as it is written: “Let us make the human…”

8But a dream mediated by a SheiD (demon) corresponds to the animal level, as in “and the ShoD (pillaging) of animals will destroy you” (Habakkuk 2:17).

9And this is: {“Men do not abide in honor; they are comparable to the animals nidmu (in their likeness)” (Psalms 49:13) .}

10Men do not abide in honor”—this alludes to a person who does not abide and sleep “in honor,” in the concept of tefilin, as discussed above. In other words, when he fails to refine the intellects, the concept of tefilin, then “comparable to the animals niDMu”—the power of the meDaMeh (imagination) corresponds to the animal level, a dream mediated by a demon, which is synonymous with the animal level.

11Thus the letters of MaLAKh (angel) are the first letters of “Ki LeiElohim Mageeney Eretz (for the Guardians of the Earth belong to God)” (Psalms 47:10). By rectifying the intellects and the tefilin, the Guardians of the Earth create the concept of an angel, which in turn results in a dream mediated by an angel.
