We must always compare one garment to another in terms of which one clothes a greater part and will therefore be subject to greater action than one that clothes a small part. Moreover, through this principle we can understand in great detail how the various powers are clothed differently in one another. When we want to make a precise measurement of the power of the action of the higher Partzuf, we measure which limbs or parts of a limb are clothed in the lower Partzuf and their characteristics and we then understand the quality of the action. (The quality of the action depends not only on how much of the wearer is clothed but also on which limb or part of a limb – i.e. which Sefirah or part of a Sefirah – is clothed.)
