Idra


The Idra, which means threshing floor in Aramaic, is a Kabbalistic work included in printings of the Zohar, and was probably written and appended to the main body of the Zohar at a later date. Contemporary scholars believe the Idra dates to the third generation of Zoharic literature, which produced also the Tikunei haZohar, the Ra'aya Meheimna, and other Zoharic material. The main body of the Zohar, or guf ha-zohar, dates to the second generation of Zoharic material.
There are actually two texts in Zoharic literature called Idra: the first being the Idra Rabba, or "greater Idra", and the second being the Idra Zuta, or "lesser Idra", with these two texts being intimately connected to each other.
The story of the Idroth is as follows:
In the standard printed edition of the Zohar, the Idra Rabba is printed in Naso, and the Idra Zuta is printed in Ha'azinu.

Lurianic systemisation of the Partzufim

16th century Lurianic Kabbalah systemised the Zoharic Partzufim in its recasting of the whole Kabbalistic scheme. On one occasion, as recorded by Chaim Vital, Isaac Luria convened his students in the traditional location of the Idra Rabba Assembly near Meron, placing each one in the designated location of their former incarnations as the students of RASHB"I. In so doing, he identified himself with Shimon Bar Yohai.
