 Eckhart generally followed Thomas Aquinas's doctrine of the Trinity, but Eckhart exaggerated the scholastic distinction between the divine essence and the divine persons.The very heart of Eckhart's speculative mysticism, according to Royce, is that if, through what is called in Christian terminology the procession of the Son, the divine omniscience gets a complete expression in eternal terms, still there is even at the centre of this omniscience the necessary mystery of the divine essence itself, which neither generates nor is generated, and which is yet the source and fountain of all the divine.The Trinity is, for Eckhart, the revealed God and the mysterious origin of the Trinity is the Godhead, the absolute God.
