I think this sounds like a very good idea. Actually, because I like it so much, I want to ask you another question. I think I'm pretty good at visualizing. The 'undrawn landscape' refers metaphorically to things like this: I have a guy - he's an administrator in a castle, competent, a bit solitary, maybe too comfortable - and he's a foreigner - it's winter morning & he's going through his papers and one of them has something written on it that is out of the ordinary. What's written on that paper (or parchment?) is the kind of undrawn landscape that I'm talking about.
I know what this guy looks like, what he's wearing, his name, the book's title, I know what the landscape around the castle is like, but try as I might, I fail utterly to get any clarity or intuition concerning what that communication might be about. (What ever it is, it would be part of the story-advancing mechanism - that problem that the MC has to solve... I know that much. & that might be part of why I'm so anxious about it and getting stuck there...)
I was wondering, given the very interesting suggestion you made, if you might have anything that might help for a problem like the one I describe.
I wonder if you've read Natalie Goldberg's Writing Down The Bones? I've found it very useful in all sorts of ways but the main point is that when you sit down to write you keep your pen moving no matter what, and you use everything you have to to keep that happening. So if you're distracted by a dog barking nearby you write something like, "there's a dog barking and it's pulling my concentration away from this thing I should be writing, which is about a woman in a garden and she doesn't have a dog but if she did it would be small and dark and angry and..."
She gives a lot more than that in her books, and is very helpful. Some people really don't like her work, but I have gained a lot from it.
If you are struggling to hear what the man you describe is telling you, there are ways round that. It might be that he has nothing to tell you. He could be vaccuous and dull and entirely without opinion. In which case you could write about what people think of him, or about the papers on his desk, or about how he sits there all day looking out of the window and making a point to ignore you. Or you could ask him why he's not talking to you. It might be that he's being very secretive about the papers on his desk, or that he can't read so doesn't know what's on them, or that they're in a language which is foreign to him.
There are all sorts of ways you can go with this. But I know it's not helpful for me to tell you this bit! What's happening is you're seeing him, you're reaching that problematical part of the story again and again, and you're panicking and freezing. You might find it useful to abandon this part of the story for now, and write a different scene. It could be that you don't need to write this part, or don't need to write it yet. But if you absolutely have to, then this is where meditation comes in (for me, at least).
Also, I would be very grateful if you might have some suggestions for meditation. (I don't really do much of it so I'm not sure how to do that part of you suggestion)
And - I wanted to say thanks again for sharing that idea.
When we feel our inner editor peering over our shoulders, telling us stuff like, "that's not very good," or, "you can't do this, can you?" what we're doing is being far too hard on ourselves. We're judging ourselves, and telling ourselves we are failures. The answer, therefore, is to be kinder to ourselves! It sounds obvious, and far too easy to be helpful. However, I have spent a lot of time looking into the mechanics of writers' block, and (without sharing several thousand words of research and interviews, etc) I'm convinced that a lack of self compassion is at the root of it.
When writing is going at its very best, writers reach a state of almost trance-like concentration. The writing seems to flow, effortlessly and beautifully. It's glorious when you're there, but so very difficult to reach this point with any regularity. Again, I've researched this over the years and the most effective way to reach this state is through regular mediation. I've used hypnosis and self-hypnosis too, but I am ridiculously easy to hypnotise, so it's not necessarily the best route for everyone. The hypnotic trance state is very similar to the "flow" state, though, so you could consider it.
If you bring these two strands together (the lack of self compassion, and the flow state) it stands to reason, therefore, that a relatively easy fix is to try out some self compassion meditation.
I've worked with a few blocked writers over the years using these principles, and it's worked for all of them.
Google something like "free self compassion meditation" and you'll find hundreds of results. Some are great, some are awful. The ones I like you might find horrid. But there are so many out there that it doesn't matter. Find someone whose voice you like, and have a go. I find just five or ten minutes before each writing session works a treat. If I couple that with a long walk first, it goes even better. And what's great is that it's cumulative. The more you do it, the better it gets. Just trust in the meditation, and if it doesn't work recognise you've done your job: you've turned up, you've meditated, you've written, so you've succeeded. Don't fall into the habit of being angry with yourself for not writing enough, or well enough: that's what leads to blocks in the first place.
Is that a help? I hope so.
