Likutei Moharan, Part II 5:8/ליקוטי מוהר"ן·תנינא ה׳:ח׳

18. This creates proper words to revive and restore the fallen souls. There are fallen souls that need to be revived and restored by means of all types of maT’AMim (tasty treats) that restore the soul, as in “Sustain me with dainties, drape me in [the fragrance of] apples, for I am love-sick” (Song of Songs 2:5). Through the rectification and refining of the intellects by the Guardians of the Earth, pure words are made to revive them.

2This is because the mind is revealed primarily in speech, as it is written “from His mouth come daat and discernment” (Proverbs 2:6). Therefore, when the intellects are refined, proper words are made with which to restore the fallen souls, as in “seven who respond with good counsel” (ibid. 26:16). In other words, the tefilin /intellects, which are the Seven Shepherds, create the “seven meShiVei TaAM (who respond with good counsel)”—i.e., the proper words with which meShiVin (one restores) the fallen souls, as in “Seven times a righteous man falls and gets up” (Proverbs 24:16).

3This is also the meaning of “The words of God are pure words… refined sevenfold” (Psalms 12:7). This refers to the pure words made by refining the intellects—i.e., the concept of tefilin /Seven Shepherds that create the “seven who respond with good counsel.” This is the meaning of “refined sevenfold.”
