Zohar and Nefesh HaChayim

Text 1 (Nefesh HaChaim) emphasizes kavanah as elevation and adhesion of the soul in prayer—'להעלות ולדבק בתפלתו את נפשו למעלה' (raising and bonding one's soul upward through prayer). Text 2 (Zohar) describes mystical vision and auditory perception during prayer ascent, focusing on sensory mystical experience ('שמע קול גדפי דכרוביא'). Both texts affirm soul-elevation in tefillah, but Text 1 prioritizes intentional kavanah as the mechanism for adhesion, while Text 2 emphasizes the mystical perceptions accompanying ascent. The disagreement is subtle—both accept soul elevation, but differ in whether kavanah drives experience or experience accompanies devoted prayer.
