Sefer Etz Chaim and Tanya

Both texts acknowledge shevirat-hakelim and nitzotzot falling into klipot. Text 1 (Etz Chaim) debates whether only Keter of Malkhut broke or all aspects descended, emphasizing the ontological necessity that all dimensions (בחי') must have fallen. Text 2 (Tanya) focuses on how fallen nitzotzot from shevirat-hakelim specifically in Chokhma (אחוריים של חכמה דקדושה) become clothed in klipat nogah, emphasizing the mechanism of spiritual contamination and teshuvah potential. The disagreement is subtle: Etz Chaim stresses comprehensive descent of all sefirot; Tanya emphasizes selective elevation through wisdom's broken sparks. Different theological priorities rather than direct contradiction.
