SHAVASANA ( Dead body pose )

Lie flat on your back, feet comfortably part, arms and hands extended about six inches from the body, palms upwards and fingers half-folded. Close your eyes. Begin by consciously and gradually relaxing every part and each muscle of the body ; feet, legs, calves, knees, thighs, abdomen, hips, back, hands, arms, chest,shoulders, neck, head and face.
Relax yourself completely feeling as if your whole body is lifeless. Now concentrate your mind on breathing rhythmically as slowly and effortlessly as possible. This creates a state of complete relaxation. Remain motionless in this position, relinquishing all responsibilities and worries for 10 to 15 minutes. Discontinue the exercise when your legs grow numb.
This asana helps bring down high blood pressure, and relieves the mind, particularly for those who are engaged in excessive mental activity. This exercise should be done both at the beginning and at the end of the daily round of yogic asanas. During a fast, shavasana soothes the nervous system.
