The writings are meant to be studied from three distinct points of view: religious philosophy, material for the study of those states between mind and body such as ecstasy and trance, and for the sake of their mysticism. Drawn from the writings and teachings of Saint Augustine, Saint Gregory and Saint Bernard, the writings form a coordinated body of doctrine with what three great teachers of mystical theology in the Western Church have written concerning their own religious experience and the theories they based on it.
