We can add further, that since the Sitra Achara contains eleven entities, because their vitalizing 'Makif' as mentioned earlier is also included as one of the eleven, therefore, as a result of refining the eleven crowns of impurities the same applies in 'Kedusha', that 'Atik' (which is not part of the ten supernal Sefiros) is drawn internally into the ten supernal Sefiros.
And this is a great ‘Chiddush’, even greater than the ‘Hamshocha’ of 'Atik' to refine lost sparks (where the ‘Hamshocha’ below is only as an impetus). From this it is understood, that in this matter (the ‘Hamshocha’ of 'Atik' drawn down internally into the ten supernal Sefiros as a result of an Avodah of refinement) also reveals HaShem’s essence (which is not defined by parameters) even more.
