Kether (Crown) — כתר

Kether is the first and highest Sefirah on the Etz Chayyim, the initial point of emanation from Ein Sof into manifest reality. The Zohar describes it as Reisha d'Lo Ityada, the 'Unknowable Head,' the divine will (Ratzon) that precedes even the distinction between Chokmah and Binah. It stands at the apex of the three pillars, beyond the reach of human intellect, accessible only through bittul — the complete nullification of selfhood. Sefer Yetzirah assigns it the first of the ten Sefirot Belimah, the 'closed' emanations whose depth has no end.
