The Corpse -- Savasana
Relaxes and refreshes the body and mind, relieves stress and anxiety, quiets the mind. Possibly the most important posture, the Corpse, also known as the Sponge, is as deceptively simple as Tadasana, the Mountain poses. Usually performed at the end of a session, the goal is conscious relaxation. Many people find the "conscious" part the most difficult because it is very easy to drift off to sleep while doing Savasana.
Begin by lying on your back, feet slightly apart, arms at your sides with palms facing up. Close your eyes and take several slow, deep breaths. Allow your body to sink into the ground. Try focusing on a specific part of the body and willing it to relax. For example, start with your feet, imagine the muscles and skin relaxing, letting go and slowly melting into the floor. From your feet, move on to your calves, thighs and so on up to your face and head. Then simply breathe and relax. Stay in the pose for at least 5-10 minutes.
