When I used to pray, I never felt like I was talking to myself. There was always that Someone who was hopefully listening. So now my internal dialogues are usually conversations with another "person", sometimes a person I know irl and sometimes an imaginary friend I've had for five years or so. (Actually I don't really talk to my imaginary friend because we exist in parallel universes and have never met "irl" in my head, if you know what I mean.) Or I'll try to solve problems of my own making, like lately I've been working on how to build a bridge across the Atlantic. And also, if I owned a buffalo, could I ride him to work on the Tollway if I velcro'ed my tolltag to his forehead?
Okay, I think I may be the one who needs the white coats.
As far as being appreciative about nature and such, I can't recall ever praying in gratitude for stuff like that. I just enjoy in silence, without words, inside or out.
If you ever get a chance read the book Mutant Message From Down Underhand which is about aborigines and their ancient ability to communicate through thought across many many miles.
I love your eclectic taste in books - definitely have to check this one out.
