Zohar and Nefesh HaChayim

Both texts describe kavanah (intention) in tefillah (prayer) as requiring elevation and connection to divine realms. Text 1 (Nefesh HaChayim) emphasizes internal nullification of bodily sensation and pouring the soul into prayer words, achieving union through linguistic vessels (תיבות). Text 2 (Zohar) describes mystical ascent with sensory experiences (hearing cherub wings, incense) and describes this as clinging/attachment (אתדבקן). The disagreement is not substantive—both mandate kavanah toward transcendence—but differs in methodology: Text 1 stresses negation of physicality and verbal precision; Text 2 emphasizes mystical perception and sensory metaphors for attachment. Different frameworks for accomplishing similar spiritual goals.
