Sarvangasana ; This is a posture in which the body is lifted topsy-turvy(upside down) and entire weight of the body rests on shoulders and elbows. This is useful for all the organs of the body, hence called Sarvangasana. This is difficult to practice in the beginning; but could be taken up after practicing the Khatwangasana for a few days. Practice the posture as shown in the picture keeping the legs as straight as possible. Eyes should be closed. Breasting should be slow and normal. The posture may be retained for 30 seconds in the first week, gradually increasing by 30 seconds every week upto two minutes. It is enough if the posture is maintained for five minutes with care. No strain should be felt in the shoulders or in the neck. The lifting up of the body and brining down should be smooth without any jerks.

Note:
The Counter Posture Matyasana should invariable be practiced for half the time given for Sarvangasana. If you practice Sarvangasana, the main posture, for 4 minutes, you must practice Matyasana or Ushtrasana, the counter - posture for 2 minutes. If this method is strictly adapted, you are sure to relax the body completely. You feel quite fresh after practicing the Sarvangasana.
