Jewish mysticism certainly suggests this, particularly when we delve into the intricate teachings of the Zohar. But where do we even begin to understand its complexities?

One helpful guide is the preface written by Baal HaSulam, Rabbi Yehuda Leib Ashlag, to his commentary on the Zohar. He helps us navigate the often-challenging terrain of Kabbalah, offering insights into how the Zohar approaches the very structure of existence.

Now, Baal HaSulam draws an important parallel. Just as we see the four worlds of Atzilut (Emanation), Beria (Creation), Yetzira (Formation), and Asiya (Action) as a general framework, he explains that this same pattern applies to every single detail within those worlds. Yes, even the tiniest aspect, from the highest realm of Atzilut down to the very end of Asiya, contains within it this fourfold structure.

How is that possible? Well, each detail, according to Kabbalah, includes the Sefirot of Ḥokhma (Wisdom), Bina (Understanding), Tiferet (Beauty), and Malkhut (Kingship/Kingdom). Think of it like this: Ḥokhma is the form, the initial spark of an idea. Bina, Tiferet, and Malkhut then become the substance that gives that form expression and tangible reality. They are like the vessel that holds the light.

And here’s where it gets even more interesting. The Zohar, according to Baal HaSulam, primarily focuses on this "substance" – that is, Bina, Tiferet, and Malkhut. It's also interested in the form as it is enclothed within the substance. Why? Because a form without substance, Ḥokhma divorced from the other Sefirot, is like an idea that never manifests – potent, perhaps, but ultimately inaccessible. And even more so, the Zohar doesn't engage with the very Essence, the Ein Sof (the Infinite), which is beyond comprehension.

So, the Zohar is intensely interested in how the divine light manifests within creation, even within the details of Atzilut itself. But it doesn't dwell on Keter (Crown) and Ḥokhma in isolation, even within Malkhut at the end of Asiya. It looks at these higher Sefirot only insofar as they are expressed and contained within Bina, Tiferet, and Malkhut.

To put it simply, Baal HaSulam is giving us a crucial key: the Zohar is all about substance and form within substance.

Furthermore, the Zohar focuses on Beria, Yetzira, and Asiya, or, put another way, the illumination of Atzilut within those lower worlds. It’s about how the divine manifests down here, in the realms of creation, formation, and action that we experience.

So, what does all this mean for us? It means that when we study the Zohar, we're not just engaging with abstract concepts. We're exploring the very fabric of reality, the way the divine light permeates every aspect of existence. We are invited to see the interconnectedness of all things, from the highest spiritual realms to the smallest details of our everyday lives. It's a reminder that the divine is not something distant and separate, but rather something that is present in every moment, waiting to be discovered.
