Health is not purely the absence of illness. Health involves Mental, Physical, and Spiritual aspects. Health is a state of stability, wellness and ease in all aspects of being, Physical, Spiritual, and Emotional.
Each of these aspects of being are intertwined. Emotional upset will affect us spiritually. Spiritual disconnect will lead us to be hardened emotionally and physically. And, physical acts of creating peace and calm lead to emotional stability, and a feeling of spiritual connection with the Creator.
We are physical beings, and our basic physical needs must be met to allow for higher functioning on a mental and spiritual level. This includes proper rest and nutrition. Inadequate, or improper nutrition, leaves us unable to think clearly, as does insufficient rest.
Our bodies also require physical activity. We were not designed to sit on our butts all day watching TV or working on the computer.
When the physical needs have been met, we can tend to our mental, emotional, and spiritual needs.
We live in a world that is not geared toward creating healthy individuals, so we must each take responsibility for our own lives and health.
