We need a mirror to see our outer self. To look within, we also need a mirror - the mirror of the other. This reflection coming from another person is a strange one - distorted and exaggerated like a circus mirror - but if we can see through the glass, we can recognize a part of ourselves that needs too be looked at. This is an often overlooked part of 'psychological projection' - when we throw our undesirable shadow traits on to another person. Then, like a movie screen, the projection is immediately reflected back. It looks like another person - and it is - but it is really a reflection of you.
