Idra Rabbaאדרא רבא

"The Great Assembly": Rabbi Shimon summons nine companions to a threshing-floor to expound, feature by feature, the anatomy of the divine Faces — the White Head, the dew-filled skull, the thirteen curls of the beard of Arich Anpin, then the black-haired features of Ze'ir Anpin. Three companions die of ecstasy mid-session, consumed by what they receive. The Zohar's high mass, and the direct source of Luria's partzufim.
