Section: Fundamentals relating to the Sefirot and their rule (Openings 14–17)
This is the chapter that introduces or yashar (direct light) and or chozer (returning light) — and with them, in passing, the first explicit mention in Klach of Tzimtzum (the cosmic contraction) and the Kav (the Line). Klach distinguishes two kinds of direct-and-returning light. The first is in governance: the Sefirot descend from Keter to Malchut, and then "Malchut becomes Keter" as the cycle returns to its Source — "I am first and I am last" (Isaiah 44:6). The whole Sefirotic structure is one complete cycle from Eyn Sof and back to Eyn Sof. Ezekiel's vision of the chayot "running and returning, like the appearance of lightning" (Ezekiel 1:14) is exactly this oscillation. The second is in hishtalshelut (the developmental chain): no light accomplishes its purpose until it descends from and returns to its Source, leaving behind a reshimu — a trace, a residue — that becomes the level itself. Each level is what is left when the root-light has come down with great power and ascended again. The chapter is also the major forecast of the Tzimtzum doctrine that arrives in full at Op. 24+: it cites Etz Chayim directly ("Everything was filled with the simple light of Eyn Sof" — Etz Chayim, Igulim VeYosher 1:11:3) and locates the entire governance "within the Tzimtzum."
This chapter introduces two of the most important technical concepts in Lurianic Kabbalah — or yashar and or chozer — and uses them to do two distinct kinds of work. The first is to show that the entire Sefirotic system is a single cycle: the apparent multiplicity of ten levels is the unity of one going-forth-and-returning from Eyn Sof. The second is to give the mechanism by which a level is generated: not just a static rung of a ladder, but the trace left behind when the root-light has descended and ascended again. The reader who works through Op. 16 will have, in vocabulary and in image, the operating model that the rest of Klach uses.
The chapter does three jobs:
Establishes the governmental cycle. The Sefirot descend Keter → Chochmah → Binah → … → Malchut. Then Malchut becomes Keter and the cycle returns to Eyn Sof. The whole ten is a single complete cycle — "I am first and I am last". The lightning of Ezekiel 1:14 makes the cycle visualisable: light flashes from one side to the other and immediately back.
Establishes the developmental mechanism. When a root-light produces a level (a "branch"), it descends with great power to where the level is to be, then ascends — leaving behind a trace (reshimu). The trace, taking its own existence, is the level. This is how every level in the Sefirotic structure was generated: by an or yashar descent followed by an or chozer ascent that left the trace behind.
Forecasts the Tzimtzum doctrine. In passing — but with a directly-cited Etz Chayim — Klach introduces Tzimtzum (the contraction) and Kav (the Line). Originally "everything was filled with the simple light of Eyn Sof"; the Tzimtzum is the concealment of that perfection; the Kav is the governmental Line that came into being after the concealment; and the goal of the entire cycle is the restoration of the original perfection. Op. 24+ will develop this in full; Op. 16 plants the terms.
Two diagrams. The first is the chain of the chapter's argument. The second is the central image: the two kinds of direct-and-returning light, side by side, with their respective scales and mechanisms.
The chain shows: proposition → governance cycle (descent + return; Malchut becomes Keter; "I am first and I am last") → lightning analogy (Ezekiel 1:14) → Eyn Sof encompasses both ends → Tzimtzum and the Kav (Etz Chayim cited) → the goal: restoration of perfection (forecast Op. 30) → developmental mechanism (descent + ascent + reshimu) → branch-and-root distinction → every level remains, built into the structure.
A side-by-side schematic. On the left: the governmental cycle — Eyn Sof above, the ten Sefirot descending Keter → Malchut, then ascending Malchut → Keter, returning to Eyn Sof. On the right: the developmental mechanism — root-light descends to the place of a level, ascends, leaving behind a reshimu (trace) that becomes the level itself.

> Two kinds of direct and returning light: in the governmental order and in the developmental chain Plain English:
The chapter is about two kinds of direct and returning light — or yashar and or chozer — operating in two different domains: in the governmental order (the Sefirot's active rule of the worlds) and in the developmental chain (hishtalshelut, the causal chain through which one level produces another).
What this paragraph does. A clean two-domain announcement. Direct light (descent) + returning light (ascent) operate in both governance and hishtalshelut. The chapter unfolds each.

> (1) After the descent of the Sefirot level by level from Keter to Malchut, Malchut in turn becomes Keter, and so on in the same way until Keter becomes Malchut. This shows the absolute control and perfection of Eyn Sof. For everything emanates from Him, and He is the end goal of everything, as it says: "I am first and I am last" (Isaiah 44:6). He is revealed as such at the beginning as at the end. The closer any given level is to Him, the more it is magnified with His Name, and what was Malchut becomes Keter. Plain English:
After the descent of the Sefirot level by level — Keter, Chochmah, Binah, … to Malchut — Malchut in turn becomes Keter, and so on in the same way, until Keter becomes Malchut.
This shows the absolute control and perfection of Eyn Sof. For everything emanates from Him, and He is the end goal of everything, as Scripture says: "I am first and I am last" (Isaiah 44:6). He is revealed as such at the beginning as at the end.
The closer any given level is to Him, the more it is magnified with His Name. What was Malchut becomes Keter.
What this paragraph does. States the first kind of direct-and-returning light: the governmental cycle. Three claims tightly bound:
(1) Cycle structure. Descent Keter → Malchut, then ascent in which Malchut becomes Keter — until the entire ten has been re-traversed in reverse and Keter becomes Malchut (the original Keter is now in the position of the lowest, since the cycle has come around).
(2) Eyn Sof at both ends. The cycle shows His absolute control and perfection. He is the source from which everything emanates and the end goal to which everything returns. Isaiah 44:6 grounds this: "I am first and I am last."
(3) The closer-to-Him principle. The closer a level is to the Source (Him), the more it is magnified with His Name. As a level approaches the Source, it takes on a name closer to Keter (the "Crown" closest to Eyn Sof). What was Malchut (Kingship — the most distal Sefirah) becomes Keter (the Crown — the proximal Sefirah).
For the beginner. This is one of the most important Klach teachings about the Sefirot. Hold the picture: the ten Sefirot are not a one-way ladder running down from Keter to Malchut. They are one cycle, and the same Sefirah can be Malchut in one accounting and Keter in another — depending on which end of the cycle you are counting from. "I am first and I am last" is the literal description: Eyn Sof bookends the cycle, and the ten are the cycle that runs between His firstness and His lastness.
The closer-to-Him principle says something deep. Levels are named by their distance from the Source. A level closer to the Source gets a name reflecting that closeness (toward Keter); a level farther gets a name reflecting distance (toward Malchut). When the cycle inverts, the names invert too — because the position changed, not the level itself.
Concepts at play:
- sefirot_class — "the Sefirot... level by level".
- keter_middah — "Keter".
- malchut — "Malchut".
- eyn_sof — "Eyn Sof... 'I am first and I am last'".
- or_yashar — implicit ("the descent").
- or_chozer — implicit ("Malchut in turn becomes Keter").

Afterwards, as it ascends, it leaves down in its place below the level in question, while the light itself goes up. The given level then remains there, built in its place within the structure, and so in the case of all of them. Plain English:

Then, as it ascends, it leaves down in its place below the level in question, while the light itself goes up. The given level then remains there, built into the structure, and so in the case of all of them.
What this paragraph does. States the second kind of direct-and-returning light: the developmental mechanism of how a level is generated. Three claims:
(1) No light fulfils its purpose without descent and return. The pattern is structural: a single descent does not produce a level; a single ascent does not produce a level; the full motion — descent followed by return — is what is needed.
(2) Light descends with great power. Not gradually-weakening force; the descent is full-power. The light reaches all the way to the bottom.
(3) On the ascent, the light leaves the level behind. As the light ascends back to the Source, it leaves something in the place to which it descended. That something is the level. The level remains there, built into the structure. The same happens for every level.
¶15-18 will unfold the mechanism in detail; ¶5 is the first statement.
For the beginner. Think of the difference between running through and placing. If a craftsman runs a tool through a workpiece without leaving anything behind, no part is placed. If the craftsman runs the tool through and leaves a piece in place, the piece is now part of the structure. Op. 16 is saying: producing a Sefirah is like placing — it requires the full motion of bringing-down and going-back, with the placed thing remaining in its proper location within the larger architecture.
Concepts at play:
- (light) — "no light accomplishes its purpose until it emerges from and then returns to its Source" (general principle).
- or_yashar — implicit ("the light descends with great power").
- or_chozer — implicit ("as it ascends, it leaves down... the light itself goes up").

> Part 2: (1) After the descent of the Sefirot level by level from Keter to Malchut, Malchut in turn becomes Keter, and so on in the same way until Keter becomes Malchut. In the vision, this looks exactly "like the appearance of lightning" (Ezekiel 1:14). A flash of lightning looks as if it comes out from one side and travels over to the other side, then immediately afterwards, it appears to turn from the other side back to the side from which it came. Similarly, all the ten Sefirot, in every place where they are, appear in this way whenever they are seen. Keter emerges first from the Source, and the levels descend one by one to Malchut. Afterwards, Malchut itself is seen to be Keter emerging from Eyn Sof. Plain English:
In the vision, this looks exactly like the appearance of lightning (Ezekiel 1:14). A flash of lightning appears to come out from one side and travel over to the other side; then immediately afterwards, it appears to turn back from the other side to the side from which it came. Similarly, all the ten Sefirot, wherever they are, appear in this way whenever they are seen: Keter emerges first from the Source, and the levels descend one by one to Malchut; then Malchut itself is seen to be Keter emerging from Eyn Sof.
What this paragraph does. Gives the visual figure for the cycle: lightning. Three claims:
(1) Lightning's apparent motion. Lightning seems to flash from one side to the other, then back. This is what the eye sees — a single sustained luminous arc with two directional appearances.
(2) The Sefirot appear this way whenever seen. In every prophetic vision of the Sefirot, the lightning-pattern is operative: descent from the Source through the ten, and return to the Source — all seen in a single integrated event, as a single unified flash.
(3) Malchut becomes Keter. The structural inversion is seen: the very Malchut at the end of the descent is seen to be Keter emerging from Eyn Sof. The cycle has come around. The names invert because the positions invert.
For the beginner. The lightning image is doing two jobs at once. First, it makes the unity of the cycle visualisable — lightning is one flash, not two. The motion outward and the motion back are one event. Second, it gives a tractable speed: lightning is immediate; the cycle is not a slow procession from Keter to Malchut and a slow return — it is all at once, in the way lightning is all at once. Whenever the prophet sees the Sefirot, the prophet sees this immediate, single, two-directional flash.
Concepts at play:
- sefirot_class — "all the ten Sefirot".
- keter_middah — "Keter emerges first from the Source".
- malchut — "Malchut itself is seen to be Keter".
- eyn_sof — "Keter emerging from Eyn Sof".
- prophetic_vision — "in the vision... whenever they are seen".

> This is because Eyn Sof, blessed be He, encompasses the Sefirot as seen in the prophetic vision both above and below. The light flashes from above and descends, spreading downwards. As it spreads, so it becomes weaker, and when it reaches the bottom it returns to the Source below – Eyn Sof, Who encompasses below. Then the light goes back and flashes from below upwards, following exactly the same path. Thus "the Chayot were running and returning like the appearance of lightning" (ibid.). Plain English:
This is because Eyn Sof, blessed be He, encompasses the Sefirot — as seen in the prophetic vision — both above and below. The light flashes from above and descends, spreading downward. As it spreads, it becomes weaker; when it reaches the bottom, it returns to the Source below — Eyn Sof, Who encompasses below. Then the light flashes back from below upward, following exactly the same path. Thus: "the chayot were running and returning, like the appearance of lightning" (Ezekiel 1:14).
What this paragraph does. Specifies the cosmological geography of the cycle. Four claims:
(1) Eyn Sof encompasses above and below. This is the chapter's most striking metaphysical claim. Eyn Sof is not merely the source above; He is also the encompassing Source below. "I am first and I am last" — first above, last below.
(2) Descent with weakening. As the light spreads downward through the Sefirot, it becomes weaker. (This refines Op. 11 ¶12's "simple light contracted into receivable form": the contracting is the weakening as the light spreads through more numerous receivers.)
(3) Return to Source below. When the descent reaches the bottom, it returns to the Source below — Eyn Sof, encompassing below.
(4) Ascent back, same path. The return ascent follows exactly the same path. The chayot's "running and returning" is exactly this oscillation.
For the beginner. "Eyn Sof encompasses both above and below" is doctrinally crucial. Klach is teaching that Eyn Sof is not spatially "up there." He is all-around. The descent of the Sefirot does not move away from Eyn Sof in any final sense; it moves through the Sefirot toward Him as encompassing below. The return is not back-toward-an-elsewhere-Eyn-Sof; it is back-toward-Eyn-Sof-from-where-the-cycle-came. The picture is not a ladder; it is a cycle between two encompassings.
This will become important at Op. 24+ (Tzimtzum), where the void itself — the cleared space within Eyn Sof's encompassment — is what the Sefirotic cycle inhabits. The Sefirot are inside the void that is inside Eyn Sof's encompassment.
Concepts at play:
- eyn_sof — "Eyn Sof... encompasses the Sefirot... both above and below" (sharpened: encompassing on both ends).
- sefirot_class — "the light... descends, spreading downwards".
- or_yashar — "the light flashes from above and descends".
- or_chozer — "the light goes back and flashes from below upwards".

> This shows the absolute control and perfection of Eyn Sof. For everything emanates from Him, and He is the end goal of everything... The whole point of this image in the prophetic vision is to show that the Sefirot are not something outside of Him in any way, for nothing exists against His will, but that His light shines in this way (within the Tzimtzum, like lightning) until it disappears. In other words, what is concealed (in the Tzimtzum) is the perfection that was in Him from the beginning (before the Tzimtzum), just as it is now (in truth, even in the phase of concealment, within the Tzimtzum, for even within the present concealment, His perfection is really in control), just as it will be at the end. Plain English:
This shows the absolute control and perfection of Eyn Sof. For everything emanates from Him, and He is the end goal of everything.
The whole point of this image in the prophetic vision is to show that the Sefirot are not something outside of Him in any way. Nothing exists against His will. His light shines in this way — within the Tzimtzum, like lightning, until it disappears.
In other words: what is concealed (in the Tzimtzum) is the perfection that was in Him from the beginning (before the Tzimtzum), just as it is now (in truth, even in the phase of concealment, within the Tzimtzum, His perfection is really in control), just as it will be at the end.
What this paragraph does. Three deeply linked moves, with the first explicit naming of Tzimtzum in Klach:
(1) The Sefirot are not outside Eyn Sof. This restates Op. 15 ¶10's simple-unity doctrine in the context of the cycle: the cycle does not move out of Eyn Sof. Nothing exists against His will; the entire cycle is within Him.
(2) His light shines this way "within the Tzimtzum." First Klach mention. The Tzimtzum is named as the zone where the lightning-cycle takes place. Outside the Tzimtzum: the simple light of Eyn Sof, no contraction, no Sefirot. Inside the Tzimtzum: the cycle.
(3) The threefold sameness of perfection. What is concealed in the Tzimtzum is the same perfection that was in Him before the Tzimtzum, is in Him now even in concealment, and will be revealed at the end. The Tzimtzum conceals but does not abolish; His perfection is really in control even now.
For the beginner. This is one of Klach's most theologically reassuring passages. The Tzimtzum is not a removal of God's perfection; it is a concealment of it. Underneath the present concealment, His perfection is really in control. What we see in the cycle is the lightning of the concealed perfection appearing within the Tzimtzum. At the end, the concealment lifts, and the same perfection that was always there is fully revealed.
This rules out a misreading of Tzimtzum as a kind of metaphysical absence. Klach is firm: no absence. Only concealment of what is always present and always in control.
Concepts at play:
- eyn_sof — "Eyn Sof... His perfection is really in control".
- sefirot_class — "the Sefirot are not something outside of Him in any way".
- tzimtzum — "within the Tzimtzum" (first explicit naming).
- prophetic_vision — "this image in the prophetic vision".

> Between the one and the other (between the initial and final perfection, within the Tzimtzum), all the Sefirot exist – they are the source of the entire government of all the worlds, for everything is included in these ten Sefirot. And what is the end goal of the entire government? The restoration of perfection (Eyn Sof, beyond Tzimtzum) as at first. Thus during the concealment, the government starts from Keter, and does not end until Malchut. And when it is complete, what is the point? The point is that the perfection, which was initially concealed, is now fully revealed. This will be discussed further below (see Opening 30). Plain English:
Between the initial and final perfection — within the Tzimtzum — all the Sefirot exist. They are the source of the entire government of all the worlds; everything is included in these ten Sefirot.

What this paragraph does. Locates the purpose of the entire Sefirotic system in the restoration of original perfection. Four claims:
(1) Sefirot exist between initial and final perfection, within the Tzimtzum. The Sefirot are not eternal or pre-Tzimtzum; they are the structure of governance within the Tzimtzum, between the original simple-light state and its restoration.
(2) Source of all governance. The Sefirot are the source of all governance of all the worlds. Everything is included in them.
(3) Goal: restoration of perfection. The end goal is the perfection, initially concealed, fully revealed. Beyond the Tzimtzum.
(4) Forecast Op. 30. This will be unfolded at Op. 30.
For the beginner. This is a major Klach teaching: the Sefirot are not the goal. The Sefirot are the means by which the original perfection is restored — that is, fully revealed. The cycle of governance moves toward a future state in which the Tzimtzum's concealment lifts and what was always there in Eyn Sof's simple light is fully revealed. So when Klach later treats the tikkun (restoration) of the Sefirot, of the Partzufim, of the worlds — all of this is in service of the restoration of the original perfection.
Concepts at play:
- sefirot_class — "all the Sefirot... the source of the entire government of all the worlds".
- tzimtzum — "between the initial and final perfection, within the Tzimtzum".
- eyn_sof — "Eyn Sof, beyond Tzimtzum".
- keter_middah, malchut — "the government starts from Keter, and does not end until Malchut".
- cycle_of_creation — implicit (the cycle's purpose).

> The prophetic vision was so instituted because all ten Sefirot are a complete cycle of government emerging from Eyn Sof, blessed be He, and returning to Eyn Sof, blessed be He. Now, if you count the levels from the concealment (Tzimtzum) onwards, the first will be Keter, the second Chochmah, and so on until the end. But if you view the steps as leading to the ultimate future revelation after the entire cycle – for this is where the entire cycle leads – the first step after the concealment is the very first to approach the end and is thus the furthest away from it. Inasmuch as it is close to the head, it is called Keter, but because it is furthest from the end, it is called Malchut. So it is in the case of all of them. Thus the descent of the worlds under the government of the Sefirot one after the other turns out to be their ascent, as will be explained presently. Plain English:
The prophetic vision was so instituted because all ten Sefirot are a complete cycle of government emerging from Eyn Sof and returning to Eyn Sof.
Now: if you count the levels from the concealment (Tzimtzum) onwards, the first is Keter, the second Chochmah, and so on to the end.
But if you view the steps as leading to the ultimate future revelation after the entire cycle — for this is where the cycle leads — then the first step after the concealment is the very first to approach the end and is thus the furthest from it. Insofar as it is close to the head, it is called Keter; but because it is furthest from the end, it is called Malchut. So with all of them.
Thus the descent of the worlds under the government of the Sefirot one after the other turns out to be their ascent.
What this paragraph does. Resolves the apparent paradox of "Malchut becomes Keter" with the two-counting picture. Three claims:
(1) One complete cycle. The vision-mode of seeing the Sefirot — as lightning, as oscillation — is because the Sefirot are one complete cycle from Eyn Sof and back.
(2) Two ways of counting. (a) From-concealment-onward: Keter is first; Malchut is last. (b) From-the-future-revelation-backwards: the same first step is now seen as furthest from the goal, hence Malchut. The same level has two names depending on the direction of the counting.
(3) Descent is ascent. The very same motion — the descent of governance from Keter through to Malchut — is the worlds' ascent toward the future revelation. The cycle is one motion with two descriptions.
For the beginner. This is the moment that the chapter's whole point lands. The descent is the ascent. When you hear later in Klach that "the worlds descend" or "the worlds ascend", do not treat these as two different processes. They are one process with two descriptions. The descent of light through the Sefirot — the apparent moving-away-from-the-Source — is the worlds' moving-toward-the-future-restoration. Same motion, two perspectives.
This is a key teaching about time in the Lurianic system. There is one cosmic process running from the concealment to the revelation, and the Sefirot are how the process unfolds. The same level can be Keter (close-to-the-Source) and Malchut (far-from-the-end) at the same moment, depending on which end of the cycle you take as your reference point.
Concepts at play:
- cycle_of_creation — "all ten Sefirot are a complete cycle of government emerging from Eyn Sof and returning to Eyn Sof".
- tzimtzum — "from the concealment (Tzimtzum) onwards".
- sefirot_class — "the worlds under the government of the Sefirot".
- keter_middah, malchut — "called Keter... called Malchut" (perspective inversion).

> As it says: "I am first and I am last" (Isaiah 44:6). This refers to His encompassing everything above and below, in order to show that He is everything. And He is revealed as such at the beginning as at the end. What this means is that in order to understand the government of the worlds, it is necessary to understand it as follows: At first, there was complete perfection – "Everything was filled with the simple light of Eyn Sof" (Etz Chayim, Igulim VeYosher 1:11:3). This perfection was then concealed (through the first Tzimtzum or "contraction"). Then the governmental order came into being (the Kav or "Line"). The end goal of the government is also complete perfection as at first (the complete revelation of His unity). Plain English:
"I am first and I am last" (Isaiah 44:6) refers to His encompassing everything above and below — to show that He is everything.
And "He is revealed as such at the beginning as at the end." This means: in order to understand the governance of the worlds, we must understand it as follows.
At first, there was complete perfection — "Everything was filled with the simple light of Eyn Sof" (Etz Chayim, Igulim VeYosher 1:11:3). This perfection was then concealed — through the first Tzimtzum (contraction). Then the governmental order came into being — the Kav (the Line). And the end goal of the governance is complete perfection as at first — the complete revelation of His unity.
What this paragraph does. This is the chapter's most doctrinally explicit paragraph. Five layered moves, with the first explicit naming of Tzimtzum, Kav, and the first explicit citation of Etz Chayim:
(1) Isaiah 44:6 read cosmically. "First and last" = "encompassing above and below" = He is everything. The Tanakh-text and the Lurianic doctrine align.
(2) Etz Chayim citation: "Everything was filled with the simple light of Eyn Sof" (Igulim VeYosher 1:11:3). This is the canonical Lurianic teaching about the pre-Tzimtzum state, and Klach cites the precise reference.
(3) First Tzimtzum. The original perfection was concealed through the first Tzimtzum (contraction). The word first signals that there will be more contractions later.
(4) Kav (Line). After the Tzimtzum, the governmental order came into being — the Kav. So the Kav = the governmental order. This is the central Lurianic image.
(5) End goal: complete revelation of His unity. The end is the same perfection as the beginning, but now revealed (not concealed). The cycle is from concealed-perfection to revealed-perfection, with the Sefirot/Kav as the operative architecture between.
For the beginner. This is the paragraph where the cosmic narrative arrives in compressed form. Memorise the four-stage picture:
(1) Pre-Tzimtzum: the simple light of Eyn Sof fills everything.
(2) Tzimtzum: the concealment / contraction.
(3) The Kav and the Sefirot: the governmental order within the cleared/concealed space.
(4) Restoration: the same perfection now fully revealed as His unity.
Op. 24+ will give the full cosmological narrative; Op. 16 ¶12 is the executive summary. The Etz Chayim citation is also worth noting: it is the first time Klach explicitly cites a non-Tanakh, non-Talmud text by direct reference. Etz Chayim (R. Chaim Vital) is now Tier-2 authority.
Concepts at play:
- eyn_sof — "Eyn Sof... 'I am first and I am last'... the simple light of Eyn Sof... beyond Tzimtzum".
- tzimtzum — "the first Tzimtzum or 'contraction'" (explicit; first time named with the word).
- kav — "the Kav or 'Line'" (explicit; first time named in Klach).
- (governmental order) — "the governmental order came into being".

> The closer any given level is to Him, the more it is magnified with His Name, and what was Malchut becomes Keter. This means that the ends turn about (from Malchut to Keter and from Keter to Malchut) and all the others change around in sequence (Yesod into Chochmah etc.). Plain English:
The proposition's closing clause: the closer any given level is to Him, the more it is magnified with His Name; what was Malchut becomes Keter. This means: the ends turn about — Malchut becomes Keter, Keter becomes Malchut — and all the others change around in sequence: Yesod into Chochmah, and so on.
What this paragraph does. Specifies the full inversion sequence: not just Keter ↔ Malchut, but every Sefirah ↔ its mirror partner. Counting from the Source-above end gives one ordering; counting from the Source-below (goal) end gives the inverted ordering. The classic mapping:
The example Klach gives — Yesod becomes Chochmah — confirms the full-inversion picture.
For the beginner. Hold the picture: every Sefirah has an inverted partner across the cycle. When the cycle inverts (when "what was Malchut becomes Keter"), every Sefirah simultaneously inverts to its partner's position. The same Sefirah seen from the Source-above end is one name; seen from the Source-below end is its inverted name. This is the structural consequence of "I am first and I am last" for the entire ten-fold structure.
Concepts at play:
- keter_middah ↔ malchut — "the ends turn about".
- (Yesod ↔ Chochmah) — "Yesod into Chochmah".
- sefirot_class — "all the others change around in sequence".

The second kind relates to how the lights are generated within the causal chain (hishtalshelut). No light is generated except through the descent of the flash (he'arah) and its subsequent ascent from there (i.e. from the place to which it descended), for then the level in question remains there, as stated below. Plain English:

No light is generated except through the descent of the flash (he'arah) and its subsequent ascent from there — from the place to which it descended — for then the level remains there.
What this paragraph does. Distinguishes the two kinds clearly:
| | First kind | Second kind | |--|--|--| | Domain | Governance of the worlds | Hishtalshelut (developmental chain) | | Mode | Constant (always operative) | Generative (produces a level) | | Result | The cycle as ongoing operation | The level remains in place |
The Hebrew word he'arah (הארה) is used here for the flash — meaning a radiation, a shining. (Same word as in Op. 13 ¶5: temunah is a he'arah from Malchut.)
The mechanism is named: no light is generated except through descent and ascent. Generation requires full motion. After the motion, the level remains.

> In other words, the light descends with great power all the way down to the bottom. When a given light has to make one or several levels, it descends faultlessly and without hindrance but rather with great power. It then ascends again, leaving behind what it leaves (i.e. a trace – reshimu – of its radiation, namely the level that remains there below). This is because what descends is the actual light of Eyn Sof, blessed be He, for all the lights emerge from Him. Since they remain there in their place (after the ascent of this great light), the individual limited light suited to that level takes on its own existence. When the great light ascends to return to its source, this part remains. This is what creates the bond connecting the lights themselves with their source. Plain English:
In other words: the light descends with great power, all the way to the bottom. When a given light has to make one or several levels, it descends faultlessly, without hindrance, with great power. It then ascends again, leaving behind what it leaves — that is, a trace (reshimu) of its radiation, namely the level that remains there below.
This is because what descends is the actual light of Eyn Sof, blessed be He — for all the lights emerge from Him. Since they remain there in their place — after the ascent of this great light — the individual limited light suited to that level takes on its own existence.
When the great light ascends to return to its source, this part remains. This is what creates the bond connecting the lights themselves with their source.
What this paragraph does. The chapter's most technical paragraph, with the explicit naming of reshimu. Five claims tightly bound:
(1) Light descends with great power, faultlessly. The descent is full-power; no diminishment as it goes down.
(2) Ascent leaves a trace. On the ascent, the light leaves behind a reshimu (trace) of its radiation. The trace is the level that remains.
(3) What descends is the actual light of Eyn Sof. All the lights emerge from Him; what descends is Him operating through this light. (This is the simple-unity doctrine in operation: the descending light is not a separate emanation but Eyn Sof's own light.)
(4) The trace takes on its own existence as a limited light. The reshimu — left in place — takes on its own existence as the individual limited light suited to that level. So the level is not the great light itself; it is the limited light appropriate to this position in the structure, generated by the great light's having been there.
(5) The reshimu creates the bond. Because the trace is the actual remaining of the same light that descended from Eyn Sof, the trace is what connects every level back to its source in Eyn Sof. The bond between any level and Eyn Sof is the reshimu.
For the beginner. Reshimu is one of the most important concepts in Lurianic Kabbalah. The doctrine: every level in the Sefirotic structure is not a primary substance; it is a trace left behind by the actual divine light when it descended and ascended. This has two deep consequences:
(1) Every level remains connected to its source — because the trace is the same light that came from the source. There is no level that is cut off; every level is bonded to Eyn Sof through the reshimu.
(2) Every level is "limited" relative to the original light — because the trace is a partial remainder, not the full light. The light is suited to that level — appropriate to the level's place in the structure.
This same reshimu doctrine will recur at the cosmic scale at Op. 24+: the Reshimu (with the definite article) is the residue of Eyn Sof's simple light that remained in the void after the cosmic Tzimtzum, and it becomes the substance from which all later creation is fashioned.
Concepts at play:
- or_yashar — "the light descends with great power".
- or_chozer — "ascends again".
- reshimu — "a trace – reshimu – of its radiation" (introduced explicitly).
- eyn_sof — "the actual light of Eyn Sof... all the lights emerge from Him".
- sefirot_class — "the level that remains there below... the individual limited light suited to that level".

> For every branch is rooted in its source, and its power below is not like its power at its root above. Do not think that the way a given power appears below now is the same as its power above at source. When a power descends, its own essential root descends, for as yet the branch does not exist. After reaching the place of the branch, the root ascends, leaving the branch it produced in its place below. The branch pursues its source after the source's ascent. Plain English:
Every branch is rooted in its source, and its power below is not like its power at its root above. Do not think that the way a given power appears below now is the same as its power above at source.
When a power descends, its own essential root descends — for as yet the branch does not exist. After reaching the place of the branch, the root ascends, leaving the branch it produced in its place below. The branch pursues its source after the source's ascent.
What this paragraph does. Sharpens the branch/root distinction. Three claims:
(1) Branch ≠ root in power. Although the branch is rooted in its source, the power of the branch (in its lower position) is not the same as the power of the root (in its higher position). The branch is a limited expression; the root is the full power.
(2) The root itself descends to make the branch. When a power produces a branch, the root descends to the place where the branch will be. (Before the descent, the branch does not yet exist.)
(3) Branch pursues source. After the root ascends, the branch — left behind — pursues its source. The branch is not static; it has a direction toward its source.
For the beginner. This refines the reshimu picture. Each level is described as a branch of an upper root. The branch is not the root in miniature; it is what the root left behind. And — crucially — the branch yearns toward the root, pursuing it. This yearning of the branch for the root is why every level in the Sefirotic structure exhibits upward motion — the longing of every part for its source.
This is one of the deep teachings about desire in the Lurianic system. Every level in creation has within it the desire to return to its source. The desire is not contingent; it is built into the structure — because every level is a branch left behind by a root that ascended, and branches naturally pursue their roots. So the cosmic or chozer (the return motion) is not just a one-time event; it is the ongoing yearning of every level for what produced it.
Concepts at play:
- (branch/root distinction) — "every branch is rooted in its source, and its power below is not like its power at its root above".
- sefirot_class — "a given power... its essential root".

> Afterwards, as it ascends, it leaves down in its place below the level in question, while the light itself goes up. This is when it has to make levels: the light descends with power and then ascends. As the light ascends, so it leaves levels – the levels from which it ascends, leaving them behind. The given level then remains there, built in its place within the structure, and so in the case of all of them. For it is when the great power of the root activates the branch that the branch emerges. The branch emerges only in its proper place. The root power descends to the place of the branch, and from there ascends, leaving the branch formed there and built into the structure. The root light does the same thing (i.e. it leaves level after level) as it continues its ascent to the very end of all the levels. Plain English:
Afterwards, as the light ascends, it leaves down in its place below the level in question, while the light itself goes up.
This is what happens when the light has to make levels: the light descends with power and then ascends. As it ascends, it leaves levels — the levels from which it ascends, leaving them behind. The given level then remains there, built in its place within the structure. And so for all of them.
For it is when the great power of the root activates the branch that the branch emerges. The branch emerges only in its proper place. The root power descends to the place of the branch, and from there ascends, leaving the branch formed there and built into the structure. The root light does the same thing — leaving level after level — as it continues its ascent to the very end of all the levels.
What this paragraph does. Closes the chapter by describing how the whole structure gets built — level by level. Four claims:
(1) The light descends with power and ascends. The full motion is iterated for each level.
(2) Each ascent leaves a level. As the light ascends from one position, it leaves a level there. The level is built into the structure by the leaving.
(3) The root activates the branch by being there. The branch emerges only in its proper place — i.e., where the root descended. The root cannot produce a branch elsewhere; it must descend to the place where the branch is to be.
(4) Iterated to the very end. The same operation produces every level: the root descends, ascends, leaves the level, continues its ascent. Level after level is built in this way to the very end of all the levels.
For the beginner. Picture an enormous candle moving downward through the structure, leaving a footprint at every step, then ascending. As it descends, it touches each position with its full power; as it ascends, it leaves at each step a trace — a reshimu — that becomes the level at that position. By the time the original light has fully ascended back to its source, the entire ladder of levels exists as the residue of the descent-and-ascent. The structure of the Sefirotic system is, on this account, the totality of the residues left by the great light's full cycle.
This is a profound teaching about how the cosmos came into being. The ten Sefirot are not separate creations; they are one motion's residues. The unity of the structure is the unity of the single motion that produced it.
Concepts at play:
- or_yashar, or_chozer — "descends with power and then ascends".
- reshimu — implicit (the levels left behind).
- sefirot_class — "level after level... to the very end of all the levels".
Relationships introduced:
Op. 16's claim, in one sentence: The Sefirotic system is one complete cycle from Eyn Sof and back, with two operative kinds of direct-and-returning light — a constant cycle of governance ("I am first and I am last") and a generative mechanism in which every level is the reshimu (trace) left behind when root-light descended with great power and ascended.
Notice the four-fold synthesis the chapter accomplishes:
(1) Unity of the cycle. The ten Sefirot are one motion from Eyn Sof and back. The descent is the ascent in inversion. "I am first and I am last." Eyn Sof encompasses both ends.
(2) Visualisation by lightning. The cycle is seen as a single integrated flash — the chayot's "running and returning, like the appearance of lightning" (Ezekiel 1:14). The motion outward and back is one event in the prophet's vision.
(3) Generative mechanism. Every level is a reshimu — a trace, a residue — left behind when the root-light descended and ascended. The level is not the root; it is what the root left. The level pursues its root.
(4) Cosmological narrative. The first explicit mention of Tzimtzum and Kav in Klach. The full picture: pre-Tzimtzum, everything was filled with the simple light of Eyn Sof; the Tzimtzum concealed the perfection; the Kav (the governmental order, the Sefirot) came into being within the concealment; the goal is the restoration of the original perfection at the end. Op. 24+ will unfold this in full; Op. 30 will treat the goal explicitly.
The chapter is also a structural pivot for the Fundamentals unit. Op. 14 said the structure was calibrated to the goal; Op. 15 said the operation is the permitted domain of inquiry; Op. 16 now shows that the operation itself is one cycle from Eyn Sof and back. The reader who has worked through Op. 14-16 has, in concise form, the whole picture: a single calibrated cycle from Eyn Sof, through the Sefirotic structure, back to Eyn Sof, with every level being the trace of the great light's descent-and-return.
The reshimu doctrine introduced here will recur at increasing scales: per-level (here, Op. 16); per-Partzuf (when the Partzufim are developed at Op. 17+); per-world; and finally at the cosmic scale (Op. 24+: the Reshimu of the simple light that remained after the cosmic Tzimtzum). The same mechanism, deep correspondence at every scale — Klach's hallmark.
Op. 17 will now close the Fundamentals unit. Then the Partzufim treatment opens, and the dual-light vocabulary of Op. 16 becomes the operating model.
The key things this analysis must do, with verification:
tools/insert_hebrew_into_analysis.py 16 will populate this. Op. 16 has 18 Hebrew paragraphs (English at index 0 starts with para_offset = -1; P1 ↔ he[0] through P18 ↔ he[17]).analysis/diagrams/chapter_016/ — argument_chain.dot and two_kinds_of_light.dot — then tools/render_diagrams.py 16.index/concepts.json (verified for or_yashar, or_chozer, reshimu, tzimtzum, kav, sefirot_class, keter_middah, malchut, eyn_sof, hishtalshelut, cycle_of_creation).section: "Fundamentals relating to the Sefirot and their rule (Openings 14-17)". ✓Op. 16 takes the strongest move yet on the temporal architecture: Eyn Sof encompasses the Sefirot both above and below; the cycle of creation runs from Eyn Sof to Eyn Sof. The chapter cites Isaiah 44:6 ("I am first and I am last") and forecasts Op. 30 (the rule of unity that operates at the cycle's end).
