The Lightning Flash

The Lightning Flash (Seder Hishtalshelut) is the zigzag path of emanation descending through all ten Sefirot from Kether to Malkuth, tracing the order in which divine energy first structured the Etz Chayyim. It moves from Kether to Chokmah, across to Binah, down to Chesed, across to Gevurah, centering in Tiphareth, then through Netzach, Hod, Yesod, and finally Malkuth. The Sefer Yetzirah describes this as the progression of the ten Sefirot Belimah whose 'measure is ten yet they have no end.' This descending path represents the instantaneous act of divine creation — the Or Yashar (direct light) — as distinct from the Or Chozer (returning light) of contemplative ascent.
