Chapel perilous

As used in psychology

"Chapel perilous" is also a term referring to a psychological state in which an individual is uncertain whether some course of events was affected by a supernatural force, or was a product of their own imagination. It was used by writer and philosopher Robert Anton Wilson in his 1977 book Cosmic Trigger. According to Wilson, being in this state leads the subject to become either paranoid or an agnostic;[5] in his opinion there is no third way.[5] The term "chapel perilous" was used by Antero Alli, in his 1986 book, Angel Tech: A Modern Shaman's Guide to Reality Selection which is based on Timothy Leary's eight-circuit model of consciousness. In Alli's book, chapel perilous is a rite of passage, when moving between the four lower circuits of consciousness to the higher circuits.
