Adam Kadmon — The Primordial Human
The very first, most exalted form to emerge after Tzimtzum — a template of primordial humanity whose structure becomes the blueprint for every subsequent level of creation.
After Ein Sof's contraction opened the vacated space, Luria taught that the first thing to take shape within it was not the ten sefirot in their familiar form but Adam Kadmon, 'primordial Man' — the highest, purest configuration of divine light, closest of anything to Ein Sof itself. From Adam Kadmon's metaphorical 'orifices' — eyes, ears, nose, and mouth — different qualities of light emanated outward, and it was these emanations that went on to form the vessels later shattered in Shevirat HaKelim. Calling this configuration 'human' is deliberate: Lurianic Kabbalah consistently uses the human form as its template for divine structure, on the premise that Genesis's statement that humanity was created 'in the image of God' works in both directions — human anatomy mirrors a prior, cosmic anatomy. Adam Kadmon is not to be confused with the biblical Adam; it precedes physical creation entirely and functions purely as the architecture from which the Partzufim and, eventually, our own physical world are built.
