...like a general, overall providence reflecting the distinctive quality of the particular Sefirah seen in this form. This is from the standpoint of causal development (hishtalshelut). On the other hand, the straight or upright form (yosher) indicates detailed government varying according to the requirements of Kindness, Judgment and Mercy – right, left and center. In other words, the different “sides” – right, left and center – indicate Kindness, Judgment and Mercy.
When there are different “sides”, we can measure the degree to which a given force extends, assess the relative power and quality of different forces, trace their effects and make all the other distinctions that are discussed in relation to the Partzufim. Each Partzuf is an upright array of powers arranged along the lines of Kindness, Judgment and Mercy.
