In Hahnemann’s Organon of Medicine he explains in aphorism §9:
In the healthy condition of man, the spiritual vital force (autocracy), the dynamis that animates the material body (organism), rules with unbounded sway, and retains all the parts of the organism in admirable, harmonious, vital operation, as regards both sensations and functions, so that our indwelling, reason-gifted mind can freely employ this living, healthy instrument for the higher purposes of our existence.
It has been my belief, and observation over the last 20 years that this is true. In our journey of life we have obstacles and trials to strengthen our vitality and our spirit. Our spirit sings and dances when we are in situations that are for our own higher good and becomes ill when not. The worst thing about antidepressants and other psychotropic meds is that it snuffs out a persons passions/spirit and becomes very hard for that person to heal at the deepest level of the soul.
