It's very simply if you look at for example actors; they use this technique all the time! If you are supposed to act like a devastated person you can't just perform some body movement, you need to connect with your own memories of situations you have experienced that caused you to feel devastated and then go along a bit with whatever body language that may set off in you. Same in music; the player needs to develop ways to make up for the fact that while you are playing you can't hear yourself as a first-impression-listener; your listening is biased by you knowing "what's going on behind the scene". Good ways for musicians to learn this can be to have a teacher or to record a lot and listen to the recordings after some time with fresh ears.

Very nice Alain!
