Zohar and Nefesh HaChayim

Text 1 (Nefesh HaChaim) emphasizes kavanah as directional focus of the heart toward God ('צריך שיכוין לבו למקום'), stressing awareness of whom one addresses and proper intention toward supplication. Text 2 (Zohar) describes mystical ascent involving closing eyes, ascending on high, hearing celestial voices, and adhesion ('אתדבקן') through whispered speech. Both texts connect kavanah to tefillah and divine communion, but Text 1 emphasizes rational-ethical intention while Text 2 emphasizes experiential mystical union and auditory-sensory mystical phenomena.
