Look very closely into the eyes of people around you.
The muscles around the eyes and within the eyes are so revealing.

A healthy eye echoes the inner condition of the person: alert, free and child-like with curiosity and unchecked emotion.

An unhealthy eye is blank and fixed.
The spirit is walled-in behind a protective visage of fear and paranoia.
Frequently, the individual is so tense that their entire face becomes a mask; incapable of genuine, spontaneous expression.
