My research has shown me that when emotions are expressed-which is to say that the biochemicals that are the substrate of emotion are flowing freely-all systems are united and made whole. When emotions are repressed, denied, not allowed to be whatever they may be, our network pathways get blocked, stopping the flow of the vital feel-good, unifying chemicals that run both our biology and our behavior.
