Easy book to read, not very long, interesting material. I got the book with the Wholetones CD set (instrumental music), and I think the music is fantastic. I’d give the music 5 stars, and I highly recommend the entire package, great for meditation. Not sure the book would mean much to me on its own. But if you get the CDs, then I think reading through this makes sense and there’s some really good parts to it as well, especially for fellow musicians (as I am).
