 The Zohar goes into great detail describing the White Head of God and ultimately the emanation of its anthropomorphic personality or attributes.In the descending realms explained by Luria, the "Gulgalta" ("Skull"-Keter Will) within "Arich Anpin" enclothes the Chesed (Kindness) of "Atik Yomin", becoming the origin of the lights of the world of "Atzilut"; the "Mocha Stima'ah" ("Concealed Brain"-Chokhmah Wisdom) within "Arich Anpin" enclothes the "Gevurah" (Severity) of "Atik Yomin", becoming the origin of the vessels of the world of "Atzilut".The "Dikna" ("Beard") of "Arich Anpin" constricts the infinite light originating from "Atik Yomin" in 13 channels of rectification to lower, relatively finite reality.
