According to Yoga therapy the root cause of the disease lies in the Mind
@ Whenever there is a disturbance in the mind , there will be a disturbance at Physical level (eg- Anger), and whenever there is a disturbance at physical level , there will be disturbance at Mind level (eg- Head-ache). There is a close relationship between Body and Mind.
@ In all other types of treatment, only the physical body is looked after. But in Yoga Therapy, we treat at physical, pranic and mental levels. Because according to yoga therapy, the root cause of the disease lies in the mind. There is a close relationship between the body and mind. So, we treat at three levels. Moreover, man is not merely the physical body, he has got other factors like will-power, emotion, intellect and action. So, he needs treatment at all these levels, to keep total health.
