Zohar and Sefer Etz Chaim

Both texts discuss sitra-achra and middat-hadin in relation to Malkhut/Nukva. Text 1 (Etz Chaim) explains a theurgical arrangement: roots of qelipot draw from Za'ir Anpin's head (receiving light from afar, preventing attachment), while roots of dinnim are in Nukva's head (where they are sweetened by mochin and chesadim). Text 2 (Zohar) describes Nukva nursing from sitra-achra (יַנְקָא מִסִּטְרָא אָחֳרָא) during the fourth month when dinnim awaken in the world due to human sins. Text 1 emphasizes preventive separation and sweetening of judgments; Text 2 emphasizes Nukva's actual drawing/nursing from the other side during periods of judgment awakening. Both affirm that dinnim and qelipot have connection to Nukva, but Text 1 frames this as controlled arrangement while Text 2 describes it as an active process responding to cosmic/moral cycles.
