We're going to be talking about the "partition," and how it interacts with the "supernal light." Think of it as a cosmic dance, a kind of negotiation between what can be received and what must be held back.
According to Petichah LeChokhmat HaKabbalah, this partition isn't static. It has five levels, and these levels are deeply connected to something called shiurei koma. Now, shiurei koma literally translates to "dimensions of height." What does that mean? It refers to the different levels, or "heights," of light that can be enclothed within vessels, structures formed by the interaction of the light and the partition.
As the author of the Sulam (a key commentary on the Zohar) explains, the supernal light doesn't just passively enter. It impacts, it beats against the partition. Each impact is followed by a "fusion through collision," a dynamic exchange where something new is created. The partition changes with each fusion, altering the returning light, which in turn can enclothe different "heights" of light.
Think of it like this: imagine throwing a ball at a wall. The way the ball bounces back (the returning light) depends on the angle and force of the throw (the supernal light), but also on the composition of the wall itself (the partition). And each bounce, each interaction, changes the nature of both the ball and the wall, even subtly.
Now, here's a crucial point: After the tzimtzum, the initial constriction that made creation possible, the fourth level was no longer suitable for directly receiving the ten sefirot (divine emanations) of the supernal light. So, the returning light rising from the partition became the receiving vessel instead. But, and this is important, that original fourth level, with its inherent capacity to receive, still has to accompany the returning light. Without it, the returning light wouldn't be fit to serve as a vessel at all.
Why? Because the returning light, in a sense, changes the game. It introduces an element of giving, making the receiving vessel resemble the supernal light, which is all about giving. It’s this combination of receiving and giving that allows the light to be received.
It's like when you're a guest at someone's house. You're receiving their hospitality, but you accept it in a way that also gives something back – your appreciation, your company. According to this analogy, even though you're accepting a meal, you do so understanding that by accepting, you're doing your host a favor. You're still eating with your hunger (the original receiving vessel), but you're adding an element of giving to the receiving.
So, the original receiving capacity of that fourth level remains, even though it's been "disqualified" from direct reception. It combines with the giving capacity of the returning light, creating a new kind of vessel, one that can hold and reflect the divine light.
What does this mean for us? Perhaps it suggests that even our limitations, our perceived flaws or inadequacies, can become part of our capacity to receive and give. They are not obstacles, but ingredients in the ongoing process of creation, allowing us to participate more fully in the flow of divine energy. It's a powerful reminder that even in restriction, there is potential for profound growth and connection.
