I have a little VOID stone, a kind of triangle, about 10 inches long, 5 inches or so high and 3 inches thick, that sits on my desk and that I look at as I write. I discover that it's very effective in clearing most of the thoughts that I am trying to form.

That's a bit of a problem, but not an unpleasant problem at all. It seems to put me in the position where I am. My interaction with this stone brings me to certain thoughts, but it also makes me realize how unimportant they are. The VOID-stone itself, however, does not seem to me to be unimportant.
