When you are awake or asleep, the tireless action of the sub conscious mind controls all the vital functions of the body. For ex: when you are asleep, the heart continues to beat in rhythm, the process of inhalation and exhalation continues just as the same way as you are awake. However, the conscious mind interferes with the functions of the body such as heart rate, lungs, stomach and intestine by way of worry, anxiety, fear and depression. These repetitive patterns of thought interfere with the harmonious functioning of the sub conscious mind. Therefore, speaking to the sub conscious mind, giving it suggestions and commands will allow the functions of the body to get back to normal again. Whatever thoughts are conveyed to the sub conscious mind, impressions are formed in the brain cells. As soon as the sub-conscious mind accepts any idea, it starts to put it into effect immediately.
