Igul עיגול

Igul (עיגול, “circle”; plural igulim) is the first of the two modes in which the ten sefirot of every world are configured in Lurianic Kabbalah. In Chayyim Vital’s Etz Chaim (Sha’ar 1, Derush Igulim ve-Yosher — “the Discourse on Circles and Linearity”), the kav (the line of light), as it spreads into the vacated space, loops into ten concentric circles, one within another (zeh tokh zeh), “like the coats of an onion” (ke-gildei betzalim). The outermost circle, nearest the surrounding Ein Sof, is Keter; the innermost is Malkhut; and at the dead center sits the gross material world, the point furthest from the light.

The igulim are how the Lurianic system encodes graded distance from the divine source as a geometry of nested rings. Rank is read off nearness: the circle nearest Ein Sof is the most exalted, each interior circle a further remove, until the material world at the center is the most distant and therefore the most corporeal. The image is Vital’s own analogy to the concentric galgalim (spheres) of medieval astronomy, deployed while the doctrine itself remains the order of emanative descent.

Etymology

Root ‘-G-L (ayin-gimel-lamed), “round.” The noun igul is a circle or ring; the verb hit’agel is “to become round, to circle.” Vital also uses the related galgal (wheel, sphere, orbit) for the same configurations, especially when stressing the nested, rotating imagery of the astronomers. The reduplicative force of the root family (galgal, a wheel- within-a-wheel) suits the doctrine of circles within circles “without end or number.”

Place in the cosmogony

In Derush Igulim ve-Yosher the igulim arise in stages (Sha’ar 1, ch. 2). The line, beginning its descent, first forms a single round wheel; this becomes the circle of Keter of Adam Kadmon, the one most joined to Ein Sof. As the line spreads further it circles again into the circle of Chokhmah within Keter, then Binah, and so on to the tenth circle, Malkhut of Adam Kadmon. Each world then repeats the pattern: every world has ten circular sefirot, every sefirah ten more, nested without end. Crucially, the circle that must remain unjoined to the surrounding Ein Sof: were it to rejoin, “the matter would revert to what it was, and it would be nullified (mitbatel) in the light of the Infinite.” The circle is held adjacent to, but not merged with, the light that surrounds it — bound to it only through the thin line.

Notes

The pairing igulim ve-yosher (circles and linearity) is the organizing dyad of the whole discourse and of much of Lurianic cosmology after it. The two are not rival accounts but two genuine aspects (bechinot) of one reality, which is why Vital can affirm both under the rabbinic formula elu va-elu divrei Elohim chayyim (“these and those are the words of the living God”): the earlier Kabbalists who arranged the sefirot in a descending sequence and those who arranged them as a columnar figure were each describing a real configuration. The reconciliation of competing sefirotic schemata under the circle/line dyad is a Lurianic methodological signature.

A rendering note: igul is “circle” or “concentric ring,” not “wheel” in the sense of a turning rota, nor “cycle” or “orbit” — the nested structure is static, an order of distance rather than of motion.
