Holy Saturday spirituality is for in-between times. By that virtue alone, it is a holy day among holy days. Author and theologian Frederick Buechner writes that
The ancient Druids are said to have taken a special interest in in-between things like mistletoe, which is neither quite a plant nor quite a tree, and mist, which is neither quite a rain nor quite air, and dreams, which are neither quite waking nor quite sleep. They believed that in such things as those they were able to glimpse the mystery of the two worlds at once.
