The book relates to the study of spirit and spirituality; mind, intelligence, consciousness and epistemology; literature and theatre. From a basis in recorded experience it rethinks the nature of spirit and relates spirit to the human mind, and it questions the unprovable assumptions underlying contemporary objectivist and scientific approaches to intelligence, language and knowledge. It develops a model of the mind and extended states of consciousness and uses this to explore the rhythmical structures fundamental to literature and theatre.
