Kabbalah Ulangan 20:19: Sha'arei Kedusha & Reshit Chokhmah

We already explained that there is one light, in the form of man (Adam-אדם), that spreads forth in all four worlds of Emanation, Creation, Formation, and Action (Atzilut, Briyah, Yetzirah, Asiyah), until the end of the four foundational elements of this lowly world. This light adheres to the lights of Supernal Man, which is called the ten Sefirot, and they manifest within the light that is called, “the light of the source of the souls,” within which all the lower souls are included. When they descend to this world to manifest in bodies, they leave their roots, from where they were hewn, which remain in a state of adhesion above, and only the branches of those roots alone descend in a manner of spreading down. These aspects alone manifest in bodies in this world. This is compared to the branches of a tree that are bound to the tree and adhere to it, and are literally rooted in the trunk of the tree. Nonetheless, they extend and bend down, to the point that even though they are attached to the trunk of the tree, they touch the ground. When a person commits a sin for which he is liable of excision (Karet), that branch becomes severed from the body of the tree and remains separate from it. It thus remains fixed in this world like the spirit of an animal. This is the meaning of the verse,⁸⁷⁷Numbers 15:31 “For he scorned the word of HaShem-יהו״ה and broke His commandment; that person will surely be cut off, his sin is upon him.” This is also the inner meaning of the words,⁸⁷⁸Deuteronomy 20:19 “For man is the tree of the field.”

And nevertheless, the more accepted thing for the correction of the relations of Talmidei Chachamim is from Shabbat to Shabbat. Similarly it says in the Tikkunei Zohar (Sixth Correction): 10. “In any tree” (Devarim 22.6) refers to the Tree of Life, MEANING ZEIR ANPIN, FROM THE CHEST AND UP. About it is said, “She is a tree of life to those who lay hold on her” (Mishlei 3:18). And about it, ZEIR ANPIN, CALLED MAN, IS SAID, “For is the tree of the field a man” (Devarim 20:19). “in any tree” could also BE EXPLAINED AS referring to the Righteous, MEANING YESOD, FROM THE CHEST AND BELOW, of which is said, “And fruit tree yielding fruit after its kind” (Beresheet 1:11). This is the Shabbat day, when the mating of the Shechinah with the Holy One, blessed be He, takes place, then she has rest. 11. And about it YESOD, THE RIGHTEOUS, is said, “And he shall be like a tree planted by streams of water, that brings forth its fruit in its season” (Tehilim 1:3). This is the righteous people’s time to perform marital duty, the night of Shabbat. Since from the Righteous, THAT IS YESOD, CALLED THE SIXTH DAY, new souls bloom in Yisrael on the eve of the Shabbat, referred to as ‘new faces.’
