books as spiritual paths

A noticeable occurrence for me is how influential books and articles seem to keep coming into my orbit just at the time that I'm open to/needing them. From the time I was in an airport heading to my first job as an elementary teacher and ran into the book Teacher by Sylvia-Ashton Warner in the airport bookshop--a book that seemed very odd to be there, but was one of the all-time influences on my teaching--I've started to ponder how this happens. What book supplier thought this would be a good book to put in an airport? It's not the kind of book you'd expect to find there.

So I thought this may be something other Friends have noticed, and it would be interesting to hear of others' similar experiences. Also I'd love to hear what books have been influential spiritually for Friends. Right now, I'm excited by Light to Live By by Rex Ambler. Ambler had read and translatedd into modern language all of Fox's voluminous writings, and discovered that the early Quakers apparently had found a specific process to "stand still in the Light", and this book is about that process, with help "for moderns" from a similar psychological practice that came to Ambler's attention. I'd love to hear from Friends trying this process.
