I have just been reading Derren’s book ‘Tricks of the Mind’ (Channel 4 Books 2006) and he writes unknowingly on one of the principles of AT – psycho-phyiscal unity
“There is an intriguing physical correlative of this process: changing your physiology can make a marked difference in your emotional response to a troublesome thought. Find something (else) that makes you feel bad inside when you think about it……you’ll probably notice that it affects how you sit: you start slumping, or your head drops a little. Now do this. Stand up, put your shoulders back, straighten your back and look forwards and upwards. Try to feel bad about the same thing. You can’t really, can you? ‘
So let’s put that last bit into Alexander language “Now come to standing, let your neck free so that your head goes forward and up in such a way that your back lengthens and widens…….’
and I think he and i would agree.
