When people saw a mirror to look a face in a general situation, many people may think that the face in the mirror is their own face. Such situation has been shown by many dramas and movies. They also believe the face is true as a fact itself, which means a body image in the mirror shows their own ego even though the image is reverse. The other interesting thing is that we are able to see ourselves in the past only. It is due to speed of light. Every visible image depends on the light, but we are not able to perceive the speed of light. Accordingly, the body image in the mirror cannot represent the current physical existence although it becomes an image of the past existence. However, why do people make an error of perception, which is equating the image in the mirror with their ego?
