My muscles are tense. My breathes are exaggerated and heavy. There is pressure on my shoulders and neck like someone is pushing down on them. I feel constrained. These is how I feel stress or uncomfortable situations.
I felt very uncomfortable the other day when I was talking to an old friend at a coffee shop because we had a disagreement several months ago and have not really talked much since then. I started thinking there is no reason that I should be uncomfortable and awkward. So I started saying the word peace over and over in my head. I slipped more and more into a state of calmness and peacefulness.
The brain is very powerful and so is the heart for that matter. If you feel yourself getting worked up, then try just saying the word peace over and over and let it take you.
Peace, Peace, Peace
