Body LanguageThe very best instrument there is for finding out what is going on with a person is her body
The state of the body will be a reflection of her overall state
That information is very useful, both to the person herself and to a process facilitator
The best thing is if the person herself is in tune with her body and she feels what is going on with it
But even if she doesn't, the facilitator will be able to pick up much information
A person's external body language speaks volumes
By observing somebody's posture, eye movements, breathing and skin color, you can gain information about what she is doing in her mind
You can get the same information by listening to the qualities of her tone of voice
And this is without being psychic, just by looking and listening
