What does it matter? Isn't it just semantics?
It matters because what one believes determines the actions one takes. Sadly, many focus on trying to remove sickness by treating the symptoms of sickness with drugs. This is like someone trying to push darkness out of a room. The solution is not to decrease darkness, but rather to increase light. Similarily, focus on increasing health in your body because sickness is a lack of health. The solution is to increase the amount of health in the body just as we would increase the amount of light in the room. It is not sickness, it is lack of health!
Whenever a "treatment" is given, ask yourself if the focus is on treating your sickness or increasing your health. Take action to increase your health!
