How Ramchal Explains the Residue and the Hollow After Tzimtzum

Rabbi Moshe Chaim Luzzatto wrote Kalach Pitchei Chokhmah as a systematic gateway into the Lurianic account of how the worlds came to be. The work compresses long stretches of the Arizal's writings into one hundred and thirty-eight numbered gates. Two adjacent passages from that progression describe the same critical transition from different angles. The first passage explains how the lowest powers within the Unlimited joined together to form a Residue that functions as an overall Malchut and a place for created realms. The second passage describes the condition of that Residue once the Unlimited departed and the subsequent descent of the Line that filled the empty space with the ten Sefirot of Adam Kadmon.

How the Residue became an overall Malchut

The first passage opens with a structural rule that organizes the entire Lurianic account of creation. Each of the ten Sefirot contains within itself a complete set of ten Sefirot, and the tenth law in every such set is Malchut, the power that establishes existence for whatever stands below. Ramchal applies that rule to the Unlimited itself. The bottommost powers within the Unlimited each contain their own Malchut, and the bond of all those individual Malchuyot of the nine higher Sefirot produces what Kabbalistic vocabulary calls the Residue.

The result of that bond is not a mere remainder but a functioning principle. The combined Malchuyot constitute an overall Malchut, a comprehensive tenth law capable of giving existence to the worlds that will later emerge within it. Ramchal calls this overall Malchut the place of the created realms and beings, since the entire law of existence for what comes below is rooted in this single composite power.

Why the Residue counts as the root of every lower realm

Ramchal frames the Residue as the genuine root from which everything beneath the Unlimited will eventually grow. The powers that joined together to produce it were themselves the lowest aspects of the Unlimited, the edge at which the question of created existence could first arise. By gathering those edge powers into one bond and naming the result an overall Malchut, Ramchal locates the origin of the lower realms at the precise boundary where the Unlimited gives way to the possibility of something other than itself.

The framing also explains why the Residue stands as a unit rather than as a collection. The bond that produced it was a single act in which many powers cohered into one Malchut, which now functions as the foundational law for everything that descends from it.

What happened when the Unlimited departed

The second passage continues the account by describing what occurred once the Unlimited withdrew from the place where the Residue had formed. While the Unlimited held sway, everything was completely perfect, since the Unlimited itself contains no lack and admits no condition that would call for further perfection. The departure of the Unlimited revealed Malchut as a container, but that container was not at first filled with the worlds it would eventually hold. The initial revelation showed only an empty space.

Ramchal qualifies the emptiness with care. The space was not completely hollow, because the root of the worlds destined to emerge was already present within it in the form of the Residue. The Residue functioned like air within the container, occupying the space without producing any visible structure. The worlds were not yet discernible, even though their root was already in place. The word hollow applies only in relation to the perfection of the Unlimited, not in any absolute sense.

How the preservation of Ramchal's text carried the teaching forward

The passages traveled a complicated path before reaching their present standard form. Ramchal completed Kalach Pitchei Chokhmah during his final years in Padua in the early 1730s, when his kabbalistic writings were subject to a ban that restricted their circulation. The manuscript moved with him to Amsterdam and then to Acre, where he died in 1746, and copies passed quietly among trusted students. First print publication came in 1785 in Korets, nearly forty years after his death.

Twentieth century editorial work by the Ramchal Friends Society in Bnei Brak established the modern standard text and supplied the numbering of the one hundred and thirty-eight gates that subsequent scholars now cite. The two passages discussed here appear in early gates of the work and have been preserved without significant textual variation across the surviving editions.

What the Line accomplished within the hollow

The second passage closes with the next stage of the account. Once the Residue stood in place and the container appeared empty in relation to the Unlimited, the Line descended into the hollow and transformed the Residue into actual Sefirot. The entire hollow space was filled with the ten Sefirot of Adam Kadmon, as the Etz Chayim records in its first gate. The earlier hollowness gave way to the structured radiance of the first comprehensive figure of the Lurianic system.

The encompassing Unlimited remains entirely perfect throughout this process, and Ramchal repeats the point to forestall any misunderstanding. Even after the withdrawal that revealed the container and the descent of the Line that filled it, the Unlimited itself lacks no perfection whatever. What is called hollow is only that which still stands in need of perfection in relation to the Unlimited, not any condition within the Unlimited itself.

The pairing clarifies why Ramchal spent two adjacent gates on what could appear to be a single topic. The first establishes the legal status of the Residue as an overall Malchut. The second describes the condition of the place once the Unlimited departed and the action of the Line that filled the hollow with Adam Kadmon. Together they set the stage for the remaining gates to describe how the ten Sefirot of Adam Kadmon would give rise to the Nekudim, the breaking of the vessels, and the eventual restoration of Tikkun.
