Sefer Etz Chaim and Tanya

Both texts accept shevirat-hakelim (breaking of vessels) as a framework. Text 1 emphasizes the ongoing redemptive process of elevating nitzotzot (288 fallen sparks) through prayer and intention across multiple cycles until Messiah, portraying sparks as redeemable souls (בחי' הנשמות) that ascend. Text 2 focuses on how sparks from shevirat-hakelim become trapped in klipat nogah (impure shells) and defile divine faculties in human soul, emphasizing contamination rather than elevation. Text 1 stresses progressive tikkun through human effort; Text 2 stresses the descent and defilement caused by the breaking. The texts view the same cosmic event from different angles: Text 1 highlights the upward trajectory of rectification, Text 2 highlights the downward trajectory of contamination.
