Okay, so you are stuck on this feeling thing. Feelings are great. I like feelings. There is even neuroscience now something about how our feelings come first, then we rationalize them into thoughts, but that’s just my non-scientific explanation of that. In a lot of psychology, also Buddhism, and just common sense if you think about it, there are warnings to not get attached to some experience that felt good. Your attempt to recreate that will likely be frustrating. You’ve said you can’t explain it, well don’t. Why do you need to? You picked a book, you had an open mind, you had a feeling. Wouldn’t it make sense that you could go into a used book store, wonder around, and have the same thing happen again? But with a different book?
I heard a pastor explain it this way. People get a sign, they think it is from God, but instead of following it, they camp out at the sign. If you were driving to Nashville and saw a sign that said, “Nashville, 50 miles”, would you park there?
