The following is something from HeartMath’s Transforming Depression Book.
Hinge Points:
“Your emotional habits propel you to judge, blame, vent,or repress feelings, while your heart intuition whispers, “Let it go. It’s not a big deal.” This is a hinge point—a moment where you choose to go one way or another. This is where you can learn to be heart intelligent and direct your emotional energy so it won’t wash back on you with more stress. That’s how you take emotional responsibility.
Learn to increase the percentage of times you make a heart choice at the hinge points. In this way, you will build your overall heart intelligence rather than always falling back into the typical old patterns that keep compounding your stress. As your ratio of heart choices increases, your heart-intelligent thoughts will become louder and the old patterns will gradually lose strength.”
