Zohar and Sefer Etz Chaim

Both texts engage with Sefirot flow and divine emanation. Text 1 (Etz Chaim) focuses on the dynamic oscillation of Ayn Sof light through Zeir Anpin, specifically how it strikes the right side, then left side, then center, descending through yesod in a triadic rhythmic pattern. Text 2 (Zohar) emphasizes yesod as the receptive vessel blessed through three upper Sefirot (Netzach, Hod, yesod) and the Bride's (Malkhut's) relationship to these channels. Text 1 prioritizes the mechanism of light distribution and oscillation; Text 2 prioritizes the receptive capacity and sustenance flowing downward. Both acknowledge yesod's central role but approach it from different angles: Etz Chaim emphasizes dynamic circulation, Zohar emphasizes stable reception and blessing.
