Each original quality of the self or soul is specially required for nourishing and empowering one human body system. The quality of peace is responsible for taking care of the respiratory system, joy for the gastrointestinal system, love for the circulatory system, bliss for the endocrine system,knowledge for the brain and nervous system, purity for the immune system and the five senses and power for the muscular and skeletal systems.
Each one of us has at least one body system, which is most prone to disease. When our mind is under the influence of stressful emotions, there is a decrease in the flow, from the soul to this body system, of that quality which is required by it for its nourishment, which leads to the development of disease in this system over a period of time e.g. when an individual with a weak respiratory system is in a negative state of mind, there is a decrease in the flow of the quality of peace to the respiratory system which in turn can lead to a disorder like asthma.
