Atzilus is only Giluyim (revealed light of G-Dliness) and is therefore available as Pnimyus of Elokim Chayim. This applies to three levels: 1) The Sfiros (like Kochos), 2) Ratzon, 3) Koach HaHechrech [the power to create an interest in the person where there is none in the Teva (nature) of the Kochos and Ratzon].
