And in Kalach Pitchei Chokhmah, we find a fascinating glimpse into this cosmic dance.

The text tells us that the closer a level is to the Divine – to Him – the more it is magnified with His Name. Think of it like this: the closer you get to the sun, the brighter and hotter it becomes. But here's the kicker: what was once Malchut, the realm of manifestation, of kingship, actually transforms into Keter, the Crown, the highest and most sublime of the Sefirot, the emanations of God.

Mind-bending, right?

It's like the ends are constantly turning about, Malchut becoming Keter and Keter becoming Malchut. And it doesn't stop there! All the other Sefirot change around in sequence too – Yesod, the Foundation, morphing into Chochmah, Wisdom, and so on. It's a cosmic game of musical chairs! What does it mean? Perhaps, that the divine is not static, but a dynamic, ever-flowing force.

But there's more to this story. Kalach Pitchei Chokhmah speaks of two kinds of direct and returning light. The first, we're told, is constant, and governs the worlds. The second? That's where things get really interesting.

This second kind of light relates to how the lights are generated within the hishtalshelut, the causal chain, the unfolding of creation. The text emphasizes that no light accomplishes its purpose until it emerges from and then returns to its Source. In other words, every divine emanation, every spark of light, has to make a journey – a descent and an ascent.

Why?

Because no light is generated except through the descent of the he’arah, the flash, and its subsequent ascent from where it descended. Only then, Kalach Pitchei Chokhmah assures us, does the level in question remain.

Think of a deep-sea diver. They descend into the depths, experience the pressure and darkness, and then ascend back to the surface. The experience changes them. They bring back knowledge, understanding, and a deeper appreciation for the world above. Similarly, the divine light descends, illuminates, and then ascends, leaving its essence behind.

This concept of descent and ascent is crucial in Kabbalah. It suggests that spiritual growth isn't a straight line upward. It involves facing challenges, going into the "darkness," and then returning with newfound wisdom and strength. It echoes a central theme in Jewish thought of teshuvah - return. We stray, we fall, but the possibility of return, of ascent, is always open to us.

So, what does all of this mean for us, in our daily lives? Perhaps it's a reminder that change is constant. That the spiritual journey is a dance of opposites, a constant interplay between Malchut and Keter, between descent and ascent. And that even in the darkest of times, there is always the potential for light to emerge, to return, and to leave its mark on our souls.
