Kalach Pitchei Chokhmah and Tanya

Both texts discuss tzimtzum, chalal (void/empty space), and kav (line), but emphasize different aspects. Text 1 (Kalach Pitchei Chokhmah) emphasizes that chalal is relative—not absolute emptiness but rather a space lacking divine manifestation at a particular level, with reshumim (traces) present and later filled by kav. Text 2 (Tanya) emphasizes that the chalal and kav represent divine contraction creating boundaries (gevul) to enable existence (yesh), focusing on how tzimtzum creates vessels for worlds. Text 1 stresses the functional aspect of filling; Text 2 stresses the enabling of distinct existence through contraction. Both accept similar mechanisms but differ in emphasis: one on completion/fulfillment, the other on enabling/boundary-creation.
