I don’t know where much of what I write comes from. It just comes.
And sometimes I read things I have written, and they seem foreign to me.
It has likely always been like this, but now, some things are seeming less foreign. To see something, it has to have a background, and that background is a contrast. To see one thing, you need a second thing.
That actually works on many levels. The Tao Te Ching discusses this clearly.
