Holistic Approach
A holistic approach implies evaluating the physical body together with the mental and emotional aspects of a person.
How we tend to know a lot about many things (some of which are irrelevant or useless), but it is amazing how little introspection we regularly do. We are not even fully aware of our emotions. You ask a person how he or she feels, and they reply by expressing their thoughts instead of revealing the state and the nature of their emotions.
It is perfectly fine to be emotional and express the emotions rather than disguising them however if one lets the emotions seize control, it can be a pathological factor affecting the overall health. On the other side, if the body is not balanced physically, the person will then be prone to mental disorders.
Everything around and inside us changes continuously and maintaining balance holistically is not always an easy task but that is how Nature has designed us, humans. We have the innate ability to adapt and carry on and fix our own imbalances down the road.
