...so as to be joined to one another... Each part is joined with another to work in combination as required by the governmental order. Thus the different levels join together to rule in such a way that when one level is aroused, the level connected with it is also aroused. In addition, there is a spirit (רוח, ruach) that goes around through the whole body (see above, Opening 34 Part 2).
...and governed by one overall governmental law... This is the “heart” (i.e. Tiferet, the center) which, through its blood and through the spirit (רוח, ruach) within it, governs all the different limbs and organs in accordance with their individual nature. This is how the government of the entire Partzuf emerges from the root, which is the connective bond of the Partzuf through the mystery of the “understanding heart”. This is a particular facet that stands for this purpose, whereby Binah, Tiferet and Malchut are joined together, and from there the government emerges in its full depth and truth.
