Zohar and Nefesh HaChayim

Both texts discuss kavanah (intention) in tefillah (prayer), but emphasize different aspects. Nefesh HaChayim emphasizes kavanah as directed toward adding divine power to the holy worlds (להוסיף כח בקדושה) and withdrawing focus from personal needs (ולא על עניניו וצרכי עצמו כלל). The Zohar passage focuses on mystical ascent and cleaving to the supernal realms (אִתְקְשַׁר לְעֵילָּא) through sensory and auditory experience of celestial beings. Nefesh HaChayim stresses intention as self-abnegation for cosmic purpose, while Zohar emphasizes experiential mystical communion. Both involve elevation of consciousness in prayer, but the conceptual frameworks differ in focus.
