There is another element to the difference between the lower and upper partzufim. It is that each lower partzuf emerges from a different shiur koma, literally, “dimension of height,” in the five levels of the partition, as described in sections #22# and #24# above. Each lower partzuf lacks the highest level of the lights of the previous, upper partzuf and the lowest level of the vessels of that upper one. The reason for this is that it is the nature of the surrounding light to destroy the last level of opacity (ovyut) in the partition when beating upon the partition.
