““...body and mind are mutually dependent and responsive to such an amazing extent that not an eyelid flickers nor does a muscle move nor an artery throb without the knowledge of the mind, and similarly not a memory stirs, nor does a thought strike, nor an idea occur without causing a reaction in the body. The effect of disease, of organic changes in the tissues, of exhaustion, of diet, of medicine, of intoxicants and narcotics on the mind, and of pleasure and pain, sorrow and suffering, emotion and passion, fear and anxiety on the body is too well known to need mention. The close connection between the two may with justice be likened to that existing between a mirror and the object reflected in it. The least change in the object is instantaneously reflected by the mirror and conversely any change in the reflection denotes a corresponding change in the object also.””
