Sefer Etz Chaim and Tanya

Text 1 (Etz Chaim) states that Netzach and Hod are 'gufha chad' (one body/essentially unified). Text 2 (Tanya) discusses Netzach-Hod-Yesod as a distinct triad of lower sefirot that serve as vessels/garments (hitlabshut) for the higher sefirot (Chesed-Gevurah) in the context of prophecy and divine comprehension. While not directly contradicting the unity assertion, the Tanya emphasizes Netzach-Hod as a separate graduated level ('bemadrega') beneath the supernal dyad, focusing on their function as receptacles rather than their essential unity. This represents different conceptual emphasis regarding the relationship and role of these sefirot.
