On a side note, my partner who has very deep understanding of pathology applied Dr. Sarno's principles to get rid of back pain, neck pain, allergies to grass, cats, rabbits, poison ivy, constant colds, gastrointestinal intolerance of beef, etc. He demonstrated the power of knowledge. However, he would not recommend people rubbing poison ivy on their arms just for trial. He did and no rashes at all. He also buried his face into cats without any problems, while previously he would have stuffy nose and watery eyes even in a room where a cat used to be raised but not present. I wouldn't believe it if I didn't witness it.
