| from R. Fludd, Utriusque Cosmi, Vol. I [1617] (Public Domain Image) | The Cloud of Unknowing ed. by Evelyn Underhill [1922] |
This is Evelyn Underhill's translation of the medieval spiritual guidebook called The Cloud of Unknowing, written by an anonymous English monk. At the core is a mystical approach to Christian prayer, in which God is found not through rote knowledge, but through 'blind love.' It has been described as Christianity with a Zen outlook. --J.B.
