A couple of weeks ago I was my morning train to work, tired and stressed. I didn’t want to nap on the train so I decided to close my eyes and try to focus on my breathing. It is very hard to keep random thoughts from trespassing your mind. I did ok for a bit. As I was starting to feel more rested, I recalled an image from a Nova series called Fabric of the Cosmos.
I traded in one old art book on Amazon - but the others are so old or have been replaced with subsequent editions that they have no value. But books store guilt between their pages and I can’t imagine dumping them in the recycling bin. Perhaps my local used bookstore would want them?
