Purging Trapped Emotions To Lift Your Heart-Wall I was introduced to Dr. Nelson’s work through his book "The Emotion Code". I was intrigued by the concept of a "heart-wall" and wanted to remove mine. I was also curious about how this healing technique would compare to the Emotional Freedom Technique or EFT tapping technique which I have been using to release negative emotions. I have to say that the method described in "The Emotion Code" worked quite well.
