The Morning News pointed me over to this post by Nick Cave.

I liked this bit right here:

I came to understand that the sacred space is the imagination itself, or rather the time spent inside the actual idea — the song you are composing, the story you are writing, or the picture you are painting. The sacred space, for the artist, is within the creative flow, at the crucial and fiery point of artistic intention, where time suddenly contracts and the work finds its power and its groove. My sacred space became the rolling fire of the imagination.

… the “rolling fire of the imagination” is such a good line.
