Tzimtzum
If light fills everything with no empty place, how could anything separate ever form? Luria's answer: the Infinite withdrew.
Picture a light that fills everything, leaving no empty place anywhere at all. Inside that kind of total fullness, there's no room for anything separate to come into being — no gap for a single distinct thing to stand in. Lurianic Kabbalah opens right at that wall: for a world to exist, the Infinite had to <em>withdraw</em> — to contract, to pull back and clear a space where something that wasn't it could appear.
Level 2 The explanation▾
The shape of it: Ein Sof, the Infinite -> tzimtzum, the light contracting to clear a space -> a void -> the possibility of separate existence. It's a spine of Lurianic Kabbalah. The modern reading offers to hear a wider insight running through it: limitation is a condition for creation. With no boundary, no distinction, there are no separate things to begin with.
There's an echo of this in physics and information theory: for something to be real and distinct, it has to give up everything else it might have been. Limitation isn't only the price of creation — it may be its engine. An angle to think with, not a proven claim.
Level 3 Deeper▾
A classic dispute. Is the tzimtzum "literal" — an actual withdrawal of the light — or "non-literal," symbolic, true only from where we stand? Kabbalists split on it, and the reading here leans non-literal. Worth marking that as an interpretation, not a verdict.
Speculation The parallel between "tzimtzum" and "limitation as a condition for creation" in physics and information is an illuminating bridge, not a proof of any mechanism. Luria wasn't talking about information theory, and information theory doesn't fall out of Luria.
Framing
Tzimtzum is a central principle in Lurianic Kabbalah (Ein Sof -> tzimtzum -> void -> vessels).
What is open
Whether the tzimtzum is literal or symbolic — a classic dispute among Kabbalists.
Off limits
That tzimtzum is an ancient phrasing of a measurable physical or mathematical principle.
