Kalach Pitchei Chokhmah turns to Kingdom of Ein Sof.
One of the core concepts we need to understand is the idea of the "Line" (קו, kav in Hebrew). But here’s the thing: this Line, this ray of divine light, doesn't just barge in. It adapts.
Kalach Pitchei Chokhmah (Wisdom) emphasizes that the Line "accommodates itself to the Residue." What's the "Residue?" It refers to the traces of light that remain within the Vacated Space after the initial withdrawal (tzimtzum) of Ein Sof. It's like the faint scent of perfume lingering after someone has left the room.
This accommodation is crucial. Even though the light from Ein Sof is encompassing, meaning it surrounds everything, it’s not quite the same as Ein Sof itself. Ein Sof transcends all limitations, whereas the light within the Line, as it enters the Vacated Space, takes on a relationship with the "Vessel", the structures of creation that are formed within that space. In other words, the light interacts with and is shaped by the very space it illuminates.
Think of it this way: Imagine shining a flashlight into a room. The light from the flashlight fills the room, but it's also affected by the room itself. It bounces off the walls, it's absorbed by the furniture, it creates shadows. The light is still light, but it's now interacting with its environment.
The text is making a subtle but profound point: the Encompassing Light, though emanating from Ein Sof, is also within the Vacated Space. This is unlike Ein Sof, which remains outside, encompassing the entire Vacated Space from without. Ein Sof is the ultimate source, the perimeter, while the Line is the active force within creation.
So, why does all this matter? What’s the takeaway? Perhaps it's this: Even the most divine, boundless energy, when it enters into the world, takes on a relationship with that world. It adapts, it interacts, it becomes something new. And that, maybe, is a little bit like us, isn't it? We carry within us the spark of the divine, but we also exist within the world, shaped by our experiences, our relationships, and the "residue" of what has come before.
