Blame is about anger, resentment, guilt, & unresolved feelings...imagine if there were no one to direct these feelings toward, yet you still hung on to them,...would it make sense? When you stand alone & still want to say "I'm this way because of YOU"...& you feel cheated because there's no one there but yourself, & yet you still want to blame someone else...who can you blame now? Then the question is WHY would you rather hang on to the blame, that's only creating anger within you? Blaming someone else, might be easier than forgiving them, but it's not easier on your body.
Illness & disease comes from 'frozen' & trapped emotions buried deep within the unconscious,...when they cannot be released they take up residence as a physical manifestation in the body i.e.pain, anxiety, disease.
Only you can forgive, only you can let go,...only you can choose to live your life to the fullest.
