J-Heller is right. You missed the point.
Fingers are used to describe an attitude initially to give the student something to hang their hat on to - they havent seen the attitude before..they have to *learn* it. Learning it means *seeing* it, and also having a rough idea of *where* it is when they need to perform it for themselves. It is merely a teaching aid until they get the visual references ingrained in their heads...i.e. until they have learnt the visual picture.
