Elizabeth Goudge said this quote

What would normal people think if they knew what went on in a writer's mind below the surface? They'd think him even more around the bend than they had previously supposed if they could see the witches' cauldron of images and memories boiling up from the subconscious, impressions whirling in from without, ideas and insights bursting up like bubbles and gone again before they can be seized. And the hopelessness of the business, the whole infuriating, exhausting, fascinating business of grabbing something out of the turmoil and imposing upon it some faint shadow or rumor of the order, pattern and rhythm of the world.
