The essence of Malchus (Melech Hakadosh) is intrinsically exalted and inaccessible to any level of being. The external aspect of Malchus, on the other hand, encompasses creation (Melech HaMishpat). The extension of Malchus that encompasses and is exalted above creation is drawn from the essence of Malchus by the Avodah of Neshamos Yisroel, who, unlike the rest of being, are rooted in the quintessence of Malchus.
