With an over active parasympathetic nervous system a person becomes dull and gets inflicted with fears as well as an inferiority complex. With practice of asanas he becomes free from all physical and mental tension. As the nervous system is controlled by the practice of asanas it contributes to the holistic development of a person.
The conflict between wisdom and impulses is as old as time. When impulses have the upper hand a person rushes headlong into acts detrimental to his well being. But when wisdom rules, a person knows the difference between right and wrong. Practice of asanas helps strengthen his spine and brain thus reducing impulsiveness in the person.
