"To understand both the theological and spatial parameters, Davis considers the mystical experience as being not only an exclusively "inner" apprehension but also an embodied one that takes place in what she designates as "mystical space." In conception mystical space is analogous to the literary figure of the mise en abyme, an impression of infinite regress that duplicates within all its layers the qualities of the larger, initiating structure without. Such a conception acknowledges that space has been widely conceptualized through the centuries, and it allows both medieval and contemporary theories of space to be employed in examining the mystics' lives and works".
