Some complex concepts you're looking at here. For me though, I think it's even more than three faces. Even when we are alone with our selves, we are forever conscious of the fact that we cannot see all of our self. The person we are with others can sometimes reveal what we can never admit to ourselves. The esteem we seek in the eyes of others is the missing leg of the shadow we don't see, the iceberg of self that hides behind our own eyes.
