Sefer Etz Chaim and Tanya

Both texts accept tzimtzum and its role in enabling creation and divine immanence (memaleh). Text 1 (Etz Chaim) emphasizes the structural mechanics: circular/concentric emanations (igulim), the preservation of Ayin-Sof's encircling aspect (sovev), and the distinction that vessels (kelim) are themselves refined light, not literal containers. Text 2 (Tanya) emphasizes the metaphysical consequence: sequential tzimtzumim enable divine vitality to descend and clothe even inanimate matter, focusing on the 'memaleh' aspect within each level. Tanya explicitly contrasts memaleh with sovev at the end, suggesting different emphases on immanence vs transcendence, though both affirm both principles exist.
