Every disease is an inner call from the deeper levels of your consciousness. It definitely carries a message about how to improve your life, because every disease is a disagreement between the unconscious mind and the conscious mind. All the actions that we do with our conscious mind like having food, worrying about a problem, or not sleeping sufficient hours at night has to be adapted by the unconscious mind. All the involuntary actions including functioning of the heart, respiration, digestion, hormone production etc.; are governed by the unconscious mind. The unconscious mind tries to optimize all these functions according to the demands of the conscious mind. But when you consistently challenge its capability to adapt with your disturbed conscious mind, your own inner self starts troubling you. In a way it is a defense to prevent further damage to your body, mind, and soul by forcing you to stop the imbalanced way of functioning.
