The Kalach Pitchei Chokhmah, a profound text of Kabbalah, delves into just that. It explores the idea that within each Sefirah, there exists an inner essence – the pnimiyut (פנימיות), its "interiority," its soul, if you will. Think of it like this: each Sefirah isn't just a static point on a map of the divine; it's a living, breathing entity, filled with its own unique light and purpose.
This inner essence, we’re told, operates according to the "Likeness of Man." What does that mean? Well, as we'll see in later passages (and as we touched on earlier), there’s a deep connection between the structure of the cosmos and the structure of the human soul. Just as we have a body and a soul, so too does each Sefirah have a "vessel" and a neshamah (נשמה), a soul. And even within that soul, there's a "soul of the soul" – layers upon layers of divine light and consciousness.
But what breathes life into this inner essence? The text tells us it's the Line of Eyn Sof, blessed be He, that enters into it. Eyn Sof refers to the Infinite, the unknowable source of all creation. This Line, a ray of divine light, is the conduit, the connection between the limitless and the limited.
Now, here’s a key idea: Every connection between two things creates an intermediary. : when you connect two electrical wires, you need a connector. Similarly, the inner essence exists precisely because the Line of Eyn Sof enters into the Sefirah. The entry of this Line isn't just a passive event; it's an active creation.
The text describes a "brilliant radiance" shining from the Line as it enters, accommodating itself to the place it enters. This radiance? That’s the soul of the Vessel. It’s the very root of the individual mental powers, the mochin (מוחין), that define each of the different Partzufim. Partzufim (lit. "faces/profiles") are configurations of the Sefirot in a human-like form, and each one possesses its own unique mochin, its own specific way of understanding and relating to the divine.
Think of these souls as garments for the Line of Eyn Sof. The Line itself, the pure, undifferentiated divine light, remains unchanged, constant throughout all the different levels of creation. But the mental powers, the mochin, are what each Partzuf receives individually from that Line. It's like sunlight shining through different colored glass – the light itself is the same, but the experience is unique depending on the filter.
So, what does all this tell us? It suggests that the divine isn't just "out there," a distant, abstract concept. It's intimately involved in every aspect of creation, immanent within each Sefirah, within each of us. And perhaps, by contemplating the inner lives of these divine attributes, we can gain a deeper understanding of our own inner lives, our own souls, and our connection to the Infinite. It’s a call to look beyond the surface, to delve into the depths, and to discover the radiant light that shines within.
