The Celtic spiritual tradition is marked by the belief that what is deepest in us, beyond the distortions of ignorance or wrongdoing, is the image of God. Its second major characteristic is a trust in the essential goodness of creation, which it regards as a revelation of God, thus avoiding the pitfall of separating spirit and matter. The simple prayers of "Each Day & Each Night" are the new expressions of the old worlds and imagery of Carmichael's collection. It is hoped that they will help us realise anew that the life of heaven is inseparably woven into the life of earth.
