I have! I own a copy of Writing Down the Bones.

Another writer, Susan Piver, writes about both subjects. She stated in a podcast that in her experience, writing and meditation are essentially the same internal process. Arguably there are some important differences all the same, but she wouldn’t be the first to think of writing as a form of meditative attention.

Have you read any of Natalie Goldberg’s books on writing, May? She writes a lot about the relationship between writing and meditating.

I like
how you say that writing is more about attention than skill or talent;
it’s poetically succinct about so much of the writing experience. Funny,
too, because I was just thinking this about meditation the very day I
read this.

My thought was that the whole mechanism of
meditation appears to really just be two things: noticing and relaxing.
Writing works on the same mechanism, I find, and so many writers report
the same. Tap into your observations and don’t judge it, let the
creative voice finish speaking without being interrupted.

Another
link is that both activities are about letting yourself shift in to a
natural mindset, much like slowly sinking into a hot bath. It takes a
few minutes, and can be jarring at first, but the only way to get the
process working is just to start it. I waste a lot of time trying to
“prepare” my mindset before writing, only to find repeatedly that the
crucial step is to just get across that threshold.
