" Your soul is not the same thing as your emotions. We live in a world where we’re encouraged to think that our feelings dominate our lives and that we are powerless over them. But even contemporary research indicates the power God has placed in the soul to be master of our emotions. In one study, researchers presented subjects with pictures of angry faces. Half of the participants were told simply to observe the faces. The other half were instructed to label the emotion on each face. The simple act of labeling the emotion reduced its emotional impact on their own moods. It also reduced the activation of the brain region associated with strong primitive emotion. "
