Likutei Moharan 63:1/ליקוטי מוהר"ן ס״ג:א׳

1Sod Kavanat HaMilah (The Secret Meaning of the Meditations for the Circumcision):

2The brit is called amah in the Aramaic language, and this is how it is referred to in the Talmud (see Shabbat 108b). It is the aspect of an amah of six handbreadths, of which the brit is comprised.

3{“Fiery angels stood around Him; each one had six wings: with two it would conceal its face, and with two it would conceal its legs, and with two it would fly” (Isaiah 6:2).} This is the aspect of “Fiery angels stood around Him; each one had six wings.” “Six wings” are the aspect of the aforementioned six handbreadths. These are divided into three—i.e., the aspect of “with two it would conceal its face, and with two it would conceal its legs, and with two it would fly.”

4“Face” is the aspect of “and TaFaCh (struck) him on his face” (Bava Kama 32b). Thus “with two it would conceal its face” is the aspect of two TeFaChim (handbreadths), the aspect of “revealing a handbreadth and concealing a handbreadth” said in connection with the brit, as taught by our Sages, of blessed memory (Nedarim 20b) .

5Likewise, “with two it would conceal its legs” is the aspect of “and TaFaCh him on his sandal” (Bava Kama, ibid .). This too is the aspect of two TeFaChim, as explained above, [the aspect of] revealing a handbreadth and concealing a handbreadth.

6“And with two it would fly” is the aspect of birds, which were created from the mud (Chullin 27b), the aspect of “ToFeiaCh (moist) enough in order l’haTFiaCh (to moisten)” (Yoma 78a). <This too is in the two aspects of revealing and concealing, as explained above.>

7And all <these> six tefachim are encompassed and placed in the brit. For the aforementioned six handbreadths are the aspect of the six days during which God created heaven and earth, in the aspect of “Behold, You have made my days as handbreadths” (Psalms 39:6). As it is written (Exodus 20:11), “in six days God made [the heaven and earth]… vayaNaCh (and He rested) on the seventh day.” That is, all the six days, the aspect of the six handbreadths, heNiaCh (He placed) into the seventh day, Shabbat, which is the aspect of brit, as it is written (ibid. 31:16, 17), “an eternal brit (covenant), between Me and the people of Israel.”

8This is the aspect of “BeRAiShIT: BaRA ShIT (He created six)” (Tikkuney Zohar #11, p.26b), the aspect of six days, the aforementioned six handbreadths, which are all placed and encompassed in the brit .

9This is also “BeRAiShIT: BRIT AiSh (a covenant of fire)” (Tikkuney Zohar #3, p.18b)—i.e., the brit, which is comprised of six days, six handbreadths, six wings. This is “a covenant of fire”—the aspect of the fiery angels with six wings, which are the aspect of six handbreadths, as explained above. For fire too has six capacities. As the scientists explain as well, there are six capacities in fire: to soften or harden, to cook or burn, to blacken or whiten. Likewise, a bird has six capacities. By flying, it disappears or appears, is close or far way, <and is above or below>.
