This collection includes The Cloud of Unknowing, The Mystical Theology of Saint Denis, The Book of Privy Counselling, and An Epistle on Prayer. Against a tradition of devotional writings which focussed on knowing God through Christ's Passion and his humanity, these texts describe a transcendent God who exists beyond human knowledge and human language. These four texts are at the heart of medival mystical theology in their call for contion, calm, and above all, love, as the way to understand the Divine.
