Zohar and Nefesh HaChayim

Both texts address kavanah (intention) in tefillah (prayer). Text 1 (Nefesh HaChaim) presents a pedagogical progression: beginning with general devekuth of the whole soul without detailed kavanah of particulars, then advancing to kavanah of specific particulars within the soul. Text 2 (Zohar) emphasizes mystical union through sensory-mystical experience—hearing the cherubim's wings, mystical speech (lachisha)—without explicitly discussing structured kavanah development. Text 1 prioritizes intentional cognitive progression; Text 2 emphasizes experiential/auditory mystical connection. They are compatible (both seek devekuth), but differ in emphasis: Text 1 on kavanah methodology, Text 2 on mystical encounter.
