I very much thank you who did your best to answer - I likely cannot see things the way you do (or did, in Benedictus’ case) but it interests me greatly. The divisiveness of these matters is of great concern to me!
And truly:
Benedictus:
The best times are when you experience a very relaxing peace. This experience can arise at different times and places, but I often found that sitting in a dimly lit, quiet church or chapel was the most common time to feel this. I wasn’t necessarily even praying as much as I was just “experiencing” God. I still enjoy sitting in a quiet room from time to time just to clear my mind and relax.
I think I know this feeling very well, yet have never felt any need of real impulse to ascribe it to anything supernatural. I feel it very often, but in ecstasy and in contemplation (to use Catholic-ish terms).
Benedictus:
Sometimes it can be a real drag to be a believer… such as when your faith requires you to accept certain things that you don’t want to accept because they’re inconvenient or just don’t compute. I experience the former on occasion throughout my life as a Catholic and the latter as I started to drift towards agnosticism.
Well yeah, accepting the inconvenient or not-readily-apparent is always a drag. That’s true for those of us without religion too (ask any theoretical scientist, religious or otherwise!

) When I was learning basic mathematics, calculus was a hassle for me, since I did not understand the basis for its derivation. My teacher told me ‘just accept it, you’ll get it later on once you have the tools’ but noooo, I wasn’t having any of that. So she stayed after school (and I skipped work) until sundown and made me work it out the hard way. Sure wasn’t convenient, and it sure wasn’t apparent to me before I ‘did the math’, but they WERE intelligibly communicable and clearly demonstrable, and after that I aced the course. I don’t need to have faith in mathematics, I know it works and can show it - but okay, similar if not congruent, yes?
You have given me some insights, and again, I thank you for your kindnesses. I hope I can return the favor to theists who think we’re all frightful monsters. If it helps, not all nontheists ‘deny’ the supernatural, in fact, I’d say most don’t (plenty of us tend to the strong-agnostic/weak-atheist stance, which means ‘we don’t know and don’t have a reason to conclude either way, and in the meanwhile, we have plenty of other things to worry over’).
The author of this book, however, sounds pretty flakey though.
