Idra אדרא

Idra (אדרא, Aramaic, “threshing floor”) names the ritual assembly scene in the Zohar at which R. Shimon bar Yochai gathers his closest companions and delivers the most esoterically charged teachings on the inner divine life. Two principal Idra scenes are preserved: the Idra Rabba (“Great Assembly,” Zohar III, 127b-145a) and the Idra Zuta (“Lesser Assembly,” Zohar III, 287b-296b). The Idra Zuta is the death-scene of R. Shimon; the Idra Rabba is the climactic teaching scene during his lifetime. Three of the Idra Rabba’s ten companions, the narrative reports, die during the teaching itself, overcome by the disclosure.

The Idra layer is the Zohar’s most concentrated articulation of the doctrine of the partzufim, the divine countenances. Arikh Anpin (the “Long Face,” patience and mercy), Zeir Anpin (the “Short Face,” judgment and discrimination), Abba (Father) and Imma (Mother), and Nukva (the Female) are described in detail, organ by organ, hair by hair. The discourse uses the Song of Songs’s rhetoric of the divine beloved’s body and applies it to the inner anatomy of the godhead. The anthropomorphism is intentional, technically managed, and editorially distinct from the Heikhalot Shi’ur Qomah discourse: the Idra divine body is not a measurement but a symbolic anatomy, each feature corresponding to a specifiable theological function.

The Idra Rabba’s content was central to the Lurianic recoding three centuries later; the Lurianic partzufim system is the Idra material rearticulated within the tzimtzum-shevirah-tikkun frame. The Lurianic doctrine of the behinot within each partzuf, and the Cordoveran intermediate doctrine of behinot within each sefira, both depend on the Idra material as their textual foundation.

Etymology

Aramaic idra (אדרא), “threshing floor” — by metonymy, the level open space where village gatherings, including legal assemblies, take place. The Zohar uses the term both for the literal threshing-floor at which R. Shimon and companions sit in the narrative frame and for the figurative assembly-as-event.
