Writing and Drawing "In The Zone"

I'm nearing the end of my first course in drawing. Yesterday, I did something I hadn't done before except in a sketch book. I did a drawing en plein aire. I took my easel, flimsy as it is, and my large drawing pad and other supplies to a cemetery and drew a picture of the trees and tombstones and vases of flowers. Being the first time, it was enchanting indeed. In fact, after a while, I realized I was in a zone, a drawing zone. I was so wrapped up in drawing, time was not a factor. The goings on around me were not a factor. I was one with my craft.

That got me to thinking about writing. Do you ever get in a zone? Do you ever become so at-one with your writing that you zone out on everything else? The writing flows, writes itself, and you're just a medium for putting words on paper.

This is a quality of all creative work, I think--zoning out. The idea of being in a zone is not original with me. I've read a book on writing that talks about getting in a zone, the way basketball players get in a zone and they hit every shot. I did a Google search for writing in a zone and found a couple of websites incorporating the word: readwritezone and buffys write zone. I'm sure musicians and potters and painters and computer program designers and, well, almost anyone in any type of work can get into a zone.

And what occurs to me is that it is almost a spiritual experience. What do you think about all of this?
