" I wonder whether you have noticed that man is the only animal who draws his picture, his own picture. No other animal has ever done that. Not only does he draw pictures of himself, he stands before a mirror, looks at himself mirrored, reflected. Not only that, he stands before the mirror, looks at his reflection, and looks at himself looking at his reflection, and so on and so forth. Because of this, self-consciousness arises. Because of this, ego is born. "
