סימן ע"ט

This means: for it is known that the category of Man — which is a speaking living being — corresponds to the element of fire. Nitzuach [victory/conductor]: "lamnatzeiach al tashchas [for the conductor — on 'do not destroy']." Meaning: for the above blemish is the aspect of: "ki hishchis kol basar es darko [for all flesh had corrupted its way]." And so on. And it is said: "vayashcheit artzah [and he destroyed it to the ground]." And so on — as elaborated in the discourse. Therefore the complete speech — which is the holy tongue — is literally the aspect of living fiery creatures that speak. And through it the bonfire of the seventy luminaries is broken up and scattered — this being the aspect of: "burning coals shall fall upon them" [Psalms 140] — as is elaborated below in Letter Hay. There — the same Letter — regarding the perfection of the holy tongue: see the Kitzur Likutay Moharan and in Likutay Aitzos, Dibbur, Letter Gimmel — where it is explained that this means one should guard the tongue and speech from blemishing it with flawed speech, G-d forbid — of idle words, slander, lies, and the like — but on the contrary: to sanctify speech with holy words of Torah and prayer.
