Ibbur
Ibbur (Hebrew: עִבּוּר, romanized: ʿibbur, lit. 'pregnancy, impregnation, or incubation'), is one of the forms of transmigration of the soul and has similarities with gilgul neshamot "reincarnation of souls" in Rabbinic Judaism. ʿIbbur is the most positive form of possession and the most complicated.
