As we have already discussed earlier, the Partzufim are nothing but arrays in which the powers extend, ordered along the lines of Kindness, Judgment and Mercy and their levels, in all their pathways, their laws of control and their mode of government.
The ten Sefirot are ten powers and no more, and they constitute the appropriate levels of Kindness, Judgment and Mercy as discussed by the early Kabbalistic sages, the Mekubalim (Sefer Yetzirah 1:3, Rabbi Moshe Cordovero, Pardes, beginning). And these are the foundations of the entire government. But the detailed pathways of each one of these ten powers is what we call a Partzuf. There is no Partzuf without a Sefirah. This means that in order to understand matters relating to a Partzuf, it is first necessary to understand the Sefirah and to undertand its function among the other ten powers. After this, we will seek to understand its pathways in detail, and then we will understand it as a Partzuf.
