It is truly the same in the upper realms, and so you will find throughout the writings of the ARI and in all the teachings of Rabbi Shimon bar Yochai. The fundamental concept involved here is that of the mental powers (מוחין, mochin): these are the inner essence (פנימיות, pnimiyut, the “soul”) of all the Partzufim. They are the source of all government, and each Partzuf is governed by its mental powers.
These mental powers change in the Partzufim themselves at different times, thereby affecting and changing their nature and functioning, as I will explain to you below in its appropriate place. These mental powers are what we call the “garb” of this inner Line, which is the soul of the souls. It is through these different garbs that the Partzufim are distinguished from one another in all their various aspects, both qualitatively – whether they incline towards Kindness, Judgment or Mercy – and quantitatively, in terms of whether they are great or small in stature and value. For according to what they are, so they receive light from the Line garbed within them.
