Unresolved emotional pain is a killer. Literally. When we fail to let go of it, we eventually get sick. Consider cancer for example. It’s a disease that eats away at us physically when what is eating away at us emotionally (guilt, shame, bitterness, anger) becomes too much to bare.
Cancer isn’t the only one. Louise Hay wrote a terrific book about the subject. In You Can Heal Your Life she lists the emotional root cause of all disease. It’s a book that needs to be in every doctor’s office.
