Sefer Etz Chaim and Tanya

Text 1 (Etz Chaim) describes Hod and Netzach in relational terms—Hod turns upward and its light connects with Netzach and other lights. Text 2 (Tanya) emphasizes the cognitive-developmental function of Hod and Netzach as 'kidneys that counsel' and 'two eyes' in relation to transmission of intellect from father to son, focusing on refinement and densification of abstract understanding into receivable form. Both texts reference Hod and Netzach, but Text 1 frames them as conduits of light union within the sefirot, while Text 2 frames them primarily as intellectual faculties mediating the transmission and modification of paternal intellect. The difference is one of interpretive lens—structural-luminous vs. cognitive-functional.
