Murray is behind this...

In her Bedford Bits blog post, Elizabeth Wardle writes:

I’m a writing teacher, and I teach all the possibilities that help a person get words on the page. But at the end of the day, I do know that there is some aspect of writing that goes beyond all of that and is a little like magic—a magic that you can work at for a lifetime and never completely understand or perfect or even repeat. You can only be mindful and present, and ready.

And I think, that's what Murray was trying to help himself and the rest of us understand--that magic, something indescribable that he tried to describe...over and over again. He never tired of trying to understand it and he likely arrived at the same conclusion as Liz...you can only be mindful and present, and ready.
