According to Ayurveda, the ultimate goal of human being is to achieve salvation or moksha. “Dharmartha kama
mokshanam, Arogyam moolam uttamam”. Ayurveda defines Arogya as a state of equilibrium of both body and mind. One can
achieve his goal if he has a good physical strength and a healthy mind. Strength or bala is the basis of sound health & is the
inborn power to resist both physical and mental stress. If this is altered, then a person will become susceptible to disease.
