Don't be concerned about the title. It is not a boring writing about religion but it does borrow attitudes and approaches and applies them to/for the guitar student. It is a book read over and over by those that know it.
On Amazon, it can be had new for $7, used in 'very good' condition for $4. Take time to read the user reviews...72% give it five stars. And know at least one current GT instructor has encouraged GT members to read it.
Now that I have it down off the book shelf, it's time to read it again. :D
"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
