The mind creates dis-ease in the body caused by thought and the subsequent emotions that those thoughts generate.
Emotions are turbulence in the body.
Every single cell of our body is affected by our thoughts and most thoughts are the repeating daily thought patterns that are mainly negative.
Worry and fear creates this dis-ease which create physical disease.
When we become conscious and disassociated with our thoughts then the thought patterns subside and so does the dis-ease and turbulence in the body.
Mind affects the body and causes illness and sickness.
