My research explores the divinatory practices of Iraqi Yezidis as a means of accessing esoteric knowledge (ʿilmi batinî) within an oral religious tradition. I examine the use of sacred manuscripts, believed to be of heavenly origin, for prognostication and amulet creation, as well as the Yezidi institution of seers (koçek), particularly the phenomenon of “falling into book,” an altered state of consciousness, and other “literacy-related” manifestations of seer’s activities. I argue that these practices are not only vital to the community’s spiritual and mental well-being, but also provide Yezidis with a direct form of “bookish” revelation from the spiritual world in place of written sacred texts, in a cultural context where only religions of the book have historically held legitimacy.
