Here is another of Dr. Charles Tart's mindfulness exercises that is proving to be really interesting and insightful.
"Next time you are waiting become aware of what the waiting feels like. How does it feel in your body and how does it feel in your mind ? Don't think about what you are waiting for but rather the feelings aroused in and because of the waiting."
Since reading and using this exercise waiting has a whole new ' life ' for me, I'm hoping the exercise will do the same for you.
