I am involved in an ongoing discussion about whether the average person can control the chi in their body. I don't think there is a clear cut answer. In the realm of biofeedback or relaxation techniques or I guess, tai chi one can change (is that the right word) their energy, but in some of the emotional or mental health sides there really is a chemical imbalance that can't be worked out with deep breathing.
My limited understanding would be there is the practice of stress busters, but that doesn't mean one can fix themselves without some help from a practitioner. I know this is obvious, but i have a friend that is feeling guilty for not staying on top of her stress.My heart goes out to her, because it isn't always that easy to not let life, hormones, family or work have its effect on one's well being. I want to be certain in telling her it is ok to take it easy on herself.
In your work with people, how do you support people in the stress of life when there isn't an illness(yet)?
