The Corpse Pose:
Rotate your legs in and out, and then let them fall gently out to the sides.
Let your arms fall alongside your body, slightly separated from the body, palms facing upwards.
Then start stretching yourself out, as though someone is pulling your head away from your feet, your shoulders down and away from your neck, your legs down and away from your pelvis.
Breathe deeply and slowly from your abdomen.
Hold the pose for several minutes. Make your mind still and concentrate on your breath or the body.
Excellent posture, Eric...
