Sefer Etz Chaim and Tanya

Both texts acknowledge Netzach-Hod-Yesod as operative sefirot in divine flow. Text 1 (Etz Chaim) focuses on the mechanics of how Chesed rises externally, surrounds, and interacts with lower sefirot through right and left lines within the structure of lower sefirot. Text 2 (Tanya) emphasizes that even prophetic comprehension of Chesed-Gevurah occurs only through their clothing (hitlabshut) in Netzach-Hod-Yesod, because the upper midot transcend created intellect. Text 1 treats Netzach-Hod as part of the energetic circulation system; Text 2 treats them as the filter/vessel through which upper midot become knowable. Same conceptual framework but different interpretive focus: mechanics vs. epistemology.
