People suffer from two types of ills – physical and mental. Physical ailments are caused by the dis-equilibrium of the three tempers ofVata, PitthaandSleshma(air, bile and phlegm) and mental illnesses are caused by the dis-equilibrium of the three qualities of serenity, passion and inertia (Sattwa, RajasandTamas). One unique fact about these two types of illnesses is that the cultivation of virtue cures both the diseases. Physical health and mental health are interrelated. Physical health is a prerequisite for mental health and good mental health ensures physical well-being. An attitude of generosity, of fortitude in the presence of sorrow and loss, a spirit of enthusiasm to do good, and to be of service to the best of one’s capacity - these build up the mind as well as the body. The sheer joy derived from service reacts on the body and makes you free from diseases.(Divine Discourse, Sep 9, 1959)
