As yet, I haven't followed his advice, because I don't see a distinction between writing and engaging the spirit. I see writing, and living as a writer or I suppose any sort of artist, as spiritual exercise. Any artist will admit to at times slipping or plunging into a condition wherein we seem to receive the story, image, character or whatever. And all who have experienced this condition find it far more pleasant, and more likely to produce quality work, than laboring with the mind.
If someone contends that what I call inspiration is no more than a connection to a different part or function of the brain, I won't argue. I'm not trying to define or explain, only to get inspired more often and perhaps more deeply.
William Blake felt so inspired, he claimed everything he wrote came straight from God. Writers of what we call scripture probably felt the same. Maybe they were nuts. Maybe not.
Robert Pirsig, in Zen and the Art of Motorcycle Maintenance, argued that Quality is real, absolute and elemental. In my approach to the world, Quality and God are the same, and to truly seek Quality in art (or in life) is to seek God. I thought of italicizing truly, but decided that might feel preachy.
Anyway, I'm not ready to spilt my thoughts or my blog in two.
