A prime tenent of CE is that if we change the underlying energetics of the situation, then the content will change.
One way we can experience this, sitting in our chairs, is by imagining a stressful situation for 10 seconds and noticing our phsyiological state. Then we centre using 4 part centring. Then we bring that same situation back to mind.
Try it now.
Imagine a situation that has stressed you in the past couple of days. What was happening, what did you see, what was said, how were you standing/sitting? Stop after 10 seconds.
