Zohar and Nefesh HaChayim

Text 1 (Nefesh HaChayim) emphasizes Torah and mitzvot as sustaining mechanisms - the worlds depend on their performance ('תלוי בעסק התורה ומעשי המצות') for continued existence, with discontinuation leading to annihilation. Text 2 (Zohar) emphasizes Torah's intrinsic structure and divine names - Torah is inherently saturated with hidden and revealed aspects of the Holy Name ('כלה סתים וגליא'). Both affirm Torah's centrality, but Text 1 focuses on functional necessity for cosmic sustenance, while Text 2 focuses on Torah's ontological nature and symbolic perfection. The Zohar passage also adds a warning against altering Torah, grounding this in its sacred structure rather than in cosmological consequence.
