What is the main conflict in Medieval Mystics by ?

There really isn't a conflict in a narrative sense: this is a non-fiction piece. Mysticism flourished in many parts of Europe, including Germany, Italy, the Low Countries, and England, from the middle of the thirteenth century to the middle of the fifteenth. The greatest figures in Germany were Meister Eckhart, a Dominican friar of formidable intellectual gifts, and his pupils, also Dominicans, Johannes Tauler and Henry Suso. In the Low Countries, John Ruusbroec developed a Trinitarian mysticism that owed much to Eckhart, despite his apparent disagreement with the earlier teacher.
