The Cloud of Unknowing describes the contemplative method centered around eliminating all noise and images from the mind, and in that encounter with nothingness, finding God. Meanwhile, despite the austerity of the content, the style of the author is warm and congenial and eminently readable. Patrick J. Gallacher further makes this text accessible to students and teachers by including a gloss, introduction, notes, and glossary. This text gives a great introduction to the ethos of mysticism in the middle ages.
