Likutei Moharan 38:3/ליקוטי מוהר"ן ל״ח:ג׳

13. Now, it is necessary to elevate the spoken word to its source. This is the arm, the five fingers on the left hand, which are the five gevurot (severities), the five articulators. For speech is essentially from the five articulators, which are <five> gevurot, as is written (Psalms 106:2), “Who can articulate the gevurot (mighty acts) of God?” That by means of the gevurot, the spoken word is made, as is written (Psalms 145:11), “and Your gevurot, they will speak”; and as is written (Jeremiah 23:29), “Is not My word like fire, declares God.”

2And the spoken word’s elevation begins from its head—i.e., from the most select part of the truth in the word, which is called “head.” For there are a number of truths, as [the Sages] taught: Truth has been splintered (Sanhedrin 97a). And as it is written, “The head of Your word is truth” (Psalms 119:160).

3This is because before its rectification it was in an aspect of “she hurled truth to the ground” (Daniel 8:12). Thus it was impossible to speak a word of truth, because of the storm wind that confused him, as is written (Psalms 107:26), “They rise heavenward, they descend to the depths.” But when he rectifies it, then he is not confused. This corresponds to: Scripture went roundabout, [adding] nine letters, so as to avoid saying an unrefined word (Pesachim 3a). This indicates that when the storm wind is in control, a person cannot speak in a direct manner, because the <storm> wind confuses him. He has to take a roundabout path.
