Research has also shown that the higher cerebral areas of the brain are more involved with the positive states of mind than with the negative states. All living things are inherently equipped to have a complete, self-sufficient and healthy life. Ill health is an unnatural state. Unless living organisms are deprived of essential needs or have suffered injuries, they are intrinsically prepared to be free of disease. The healing process of an organism is within each living system itself, just like the process of respiration, digestion, secretion and reproduction.
Health is a natural state, because it is harmony and balance.
It is homeostasis. Externals feel their fates are in the hands of others, their environment or simply a matter of chance. They tend to be suspicious, less aggressive and less leadership-oriented than internals. Perhaps to pander to externally driven individuals, modern-day medicine men persist in promoting the idea of externality over internality. The nocebo effect is a term that illustrates a negative effect because of the power of belief.
