Step by Step:

1. Spread a blanket or a yoga mat on a plain ground or floor.
2. Lie down on it. Spread your arms 45 degrees, palms facing up. Both legs 30 degrees apart. Toes and palms should not be covered.
3. Close your eyes. Breathe slowly and relax your mind.
4. Rest for at least 5 minutes.
5. Do not fall asleep. Do not move during the posture. Try to completely relax your body, and to completely rest your mind. Your mind is awake but not moving.
6. Slowly slowly, turn your body to the left and to the right. Then wake up from your right hand side.
N.B. If you have practiced yoga postures for about an hour, at least 10 minutes savasan is necessary. If for an hour and half, 15 minutes. For 2 hours practice, at least 20 minutes. Those who work for long day they can do this asan for 15 - 20 minutes, straight after they come back home.
Sleep may give considerable rest to the body, but not necessary to the entire body, like heart and respiratory systems. Sleep does not give complete rest to the mind either. People who are worried, fearful, angry or scared can not get rid of their diseases quickly.
The root cause of all diseases is tiredness and stress. This is the only asan where you can completely relax your body, as well as the mind. A complete rest cures many diseases and ailments. Can be practied by all people, of all age, at any time of the day. By far more powerful than sleep.
