Our habitual postures are connected to habitual emotions and habitual thoughts in a strange dance – if you have a certain association, then you take a certain posture and have a certain feeling, so it’s very difficult to think anything new, to feel anything new, or to sense in a new way – if you try to change it’s impossible because each center is supported by the other two.
