If you maintain a fine grasp of this rule, you will invariably be able to tell, concerning any topic, whether we are speaking about the vessels or the lights. You will not become confused since there is always an inverse relationship between them.
We have thus fully clarified the topic of the five levels in the partition, how they lead to differences in the shiurei koma (literally, “dimensions of height” in the structure of the lights and vessels) in descending order.
Having fully clarified the concept of the partition that was placed on the vessel of Malkhut, which is the fourth level, after its constriction (tzimtzum), and the concept of the five types of fusion through collision against the partition, which produce five structures of ten sefirot, one below the other, we will now clarify the concept of the five partzufim of Adam Kadmon, which precede the four worlds of Atzilut (Emanation), Beria (Creation), Yetzira (Formation), and Asiya (Actualization).
