represents the lectures Nichifor Crainic delivered as a professor at the Faculty of Theology in Bucharest (most notably compiled during the 1920s and 1930s). This work is the theoretical backbone of Gândirism (the literary and philosophical movement he founded), blending Orthodox theology with his philosophical interests in vitalism and cultural specificity.

Another angle is the theological sources he drew upon. Did he reference classical mystics like the Eastern Orthodox ones—Ephrem the Syrian, Symeon the New Theologian—or maybe the Western mystics like Meister Eckhart? Crainic's work as a liturgist might involve the liturgy as a mystical experience, connecting the sacraments to the spiritual life.
