Is there just one “you”? We’ve been taught to believe we have a single identity, and to feel fear or shame when we can’t control the inner voices that don’t match the ideal of who we think we should be. Yet Dr. Richard Schwartz’s research now challenges this “mono-mind” theory. “All of us are born with many sub-minds―or parts,” says Dr. Schwartz. “These parts are not imaginary or symbolic. They are individuals who exist as an internal family within us―and the key to health and happiness is to honor, understand, and love every part.”
