Although he was an accomplished academic theologian, Eckhart's best-remembered works are his highly unusual sermons in the vernacular. Eckhart as a preaching friar attempted to guide his flock, as well as monks and nuns under his jurisdiction, with practical sermons on spiritual/psychological transformation and New Testament metaphorical content related to the creative power inherent in disinterest (dispassion or detachment). The central theme of Eckhart's German sermons is the presence of God in the individual soul, and the dignity of the soul of the just man. Although he elaborated on this theme, he rarely departed from it. In one sermon, Eckhart gives the following summary of his message: When I preach, I usually speak of detachment and say that a man should be empty of self and all things; and secondly, that he should be reconstructed in the simple good that God is; and thirdly, that he should consider the great aristocracy which God has set up in the soul, such that by means of it man may wonderfully attain to God; and fourthly, of the purity of the divine nature.
