A doctor's authority in America often exceeds his or her knowledge. Whole bodies of knowledge in healing are ignored because they are unorthodox and non-medical. A doctor's education seems exhaustive, yet MDs study so much about drugs and surgery - and so little about nutrition, fasting, herbal remedies, spinal manipulation, massage, vitamin and mineral therapy, homeopathy, and more - that we realize their qualifications are incomplete.
So to overcome the problems of personality the best thing is to witness, practice witnessing everything: before talking, practice witnessing, before giving any comments, just start witnessing. It's a very, very satisfying attitude.
