Describe symbolism in Reviving Ophelia by Mary Pipher

Dr. Pipher advises her young female patients to make North Star decisions. When they feel as though they are drifting in a storm of emotion and confusion, she directs them to locate true North. The North Star represents their true selves, and the voices of their parents, friends, and the media are symbolized by the winds on either side. They must listen to their true selves in order to chart their course in life.
