Think of it as the vessel, the receiver, the culmination of all the divine energies that flow down from above. But Malkhut isn't just a passive recipient. It's dynamic, complex, and holds secrets to understanding the entire system.

Specifically, we’re looking at two states of Malkhut, as illuminated in the Sulam commentary. This commentary, by Rabbi Yehuda Leib Ashlag (the Baal HaSulam), a towering figure in 20th-century Kabbalah, delves deep into the teachings of the Ari, Rabbi Isaac Luria, the father of modern Kabbalah.

The Sulam tells us that Malkhut is the mystical meaning of the Nukba of Ze’er Anpin. Okay, that's a mouthful! Let's break it down. Nukba is often referred to as the feminine aspect or "female principle." And Ze’er Anpin, meaning "Small Face" or "Short Countenance," represents the son, the active principle, the six sefirot from Ḥesed (Loving-Kindness) to Yesod (Foundation). The Nukba of Ze’er Anpin, then, is the feminine aspect that is connected to and receives from Ze’er Anpin. In other words, Malkhut acts as the Nukba to Ze’er Anpin.

The Sulam commentary further explains that the root of this Nukba begins from Malkhut of the "second constriction." This refers to a concept known as tzimtzum bet, the second act of self-limitation by the Divine. This second constriction, according to the Ari's teachings, shaped the lower worlds and made creation as we know it possible. It also concluded the seven sefirot of the immaturity of Ze’er Anpin of Nekudim.

Now, Nekudim is a complex realm – a world of "points" or "lights" that preceded our current world. Its Ze’er Anpin went through a phase of immaturity. This immaturity resulted from the ascent of Malkhut to Bina (Understanding) during that second constriction. The Nukba partzuf—the configuration of divine attributes—sits at the “bottom” of the system of partzufim (divine faces/configurations) of Nekudim (and the corresponding levels above).

This is crucial: the Nukba is a separate level from Ze’er Anpin. Why? Because Ze’er Anpin encompasses Ḥesed, Gevura (Strength), Tiferet (Beauty), Netzaḥ (Victory), Hod (Splendor), and Yesod of Nekudim. Below that level lies the Malkhut that concludes the world of Nekudim. This concluding Malkhut, therefore, is considered a distinct Nukba, separate from and below Ze’er Anpin.

So what does all this mean for us?

It highlights the intricate relationships and hierarchies within the Kabbalistic system. It shows us that even within a single sefira like Malkhut, there are different states and levels of being. It underscores the essential role of the feminine principle, the Nukba, in receiving and manifesting the divine light. And it hints at the profound depths of the Ari's Kabbalah, a system that continues to challenge and inspire us to explore the mysteries of creation.

It is a reminder that even the most seemingly simple concepts can hold layers upon layers of hidden meaning, waiting to be uncovered. And perhaps, in uncovering them, we can gain a deeper understanding of ourselves and our place in the grand tapestry of existence.
