The real prayer is your own soul-tending. It's not the writing that needs prayer - it's you. You need to find the center that is still and strengthening. You need to deal with whatever issue is dogging you today, whether it's anxiety about your teenager or resistance to the topic you are trying to write.
If you have writer's block, dig into it. You are resisting something. Something is getting in the way of your creative work. Resistance always means something.
When a writer takes on the task of exploring the world of the spirit, she has invited a process that will change her permanently. If she has done her work well, it will change her readers too.
The False Self constructs all sorts of layers of ego and angst and striving and foolishness, while the True Self, deep at the center of a person, waits for the time when the False Self will die and allow the real life to begin.
