Let's delve into a fascinating concept from the Sulam commentary, which offers a glimpse into the structure of these spiritual worlds, specifically focusing on the realm of Atzilut, often considered the world of emanation.

The text speaks of a "fourth level" and its shifting position. Think of it like this: in the very highest realm, Keter, there's only one vessel to receive divine light. Because of this, the returning light – that is, the light that bounces back and defines the boundaries of the vessel – draws out only one light, called Nefesh, the soul.

Now, according to this system, in Atzilut, only the "height of Nefesh" emerged during the initial "gestation" phase. Why? Because the initial connection, the "fusion through collision," occurred at the "forehead," which corresponds to the vessel of Keter. As explained earlier in the commentary, the "forehead" in the upper partzuf (divine configuration) represents the level of Keter, specifically gulgalta, the skull.

But things shift! After the light is drawn down during the "infancy" phase, the "fourth level" – which, as the text reminds us, is an aspect of Malkhut – moves. It ascends from the forehead to the "apertures of the eyes," which represent the first level. When this happens, the "height of Ruach" emerges. That's a step up the ladder of spiritual light.

Then comes another transformation. Through the interaction of Ḥokhma (wisdom) and Bina (understanding) in a "face-to-face" configuration within the upper partzuf, the fourth level descends back to its original place, which is Malkhut. Now, why is this so important? Because this descent facilitates the ascent of Bina, Tiferet, and Malkhut, which had previously fallen.

Remember, as we learned earlier, when Malkhut is in its elevated state, it can cut off the lower vessels from the higher lights of Ḥokhma and Keter. It's like a cosmic game of spiritual hide-and-seek! But when the "brains of the face" are activated, Malkhut can descend, allowing those lowered vessels to ascend once more.

Finally, we arrive at a complete configuration: Keter, Ḥokhma, Bina, Tiferet and Malkhut. With all five vessels present, the fourth level produces the "height of Keter" with the light of Yeḥida, the highest level of the soul. And this, according to the Sulam commentary, is the "height of Atik of Atzilut."

So, what does it all mean? Well, this intricate dance of levels and lights reminds us that the spiritual realms are not static. They're constantly in motion, interacting and influencing each other. The descent of Malkhut, seemingly a negative thing, is ultimately a crucial step in bringing about a greater illumination. It highlights the importance of even the lowest aspects of creation, and how their transformation can lead to the revelation of the highest levels of being. It’s a complex but ultimately hopeful vision, isn't it?
