years ago, i had this wonderful yoga book that had poses organized by what you wanted to accomplish -- balance, flexibility, strength, focus, etc. it also had lovely black and white photographs. it was lost some time ago, and i haven't been able to find it since -- mostly because it's so hard to find a yoga book when you don't know the author, and they're all titled the same thing. has anyone else ever used this book or something like it? i'd really love to find it again!
