Posture
In ‘Hathapradipika’ an important book on Yoga, accepts this as Mudra rather than asana. But since this very much resembles the asana position, here we have treated this as such. In this asana the body is in an inverted position and so is called Viprit Karani (inverted position).
Pre position
Supine Position.
Procedure
1        Exhale and inhaling start raising both the legs upward and stop when they make a 90 degree angle with the floor. Attain the Uttanpadasana posture.
2Â Â Â Â Â Â Â Â Exhaling raise the waist and push the legs backward over the head.
3        Inhaling, support the waist with both the hands, straighten the legs and stretch the toes towards the sky. Keep the sight on the toes.
4Â Â Â Â Â Â Â Â Continue normal breathing.
Position
In this asana, the arms up to the elbows are placed on the floor. The body from neck to the elbows is kept straight. The toes are stretched upward. Initially, if it is difficult to maintain this asana keeping the legs straight then bend the legs slightly while keeping the balance.
Releasing
1        Inhale and exhaling, slightly lower the legs towards the head and maintaining the balance of the body, remove the hands supporting the waist back to the normal position.
2        Inhaling , place the waist on the ground keeping legs straight as in the    Uttanpadasana.
3Â Â Â Â Â Â Â Â Exhaling , bring legs back to the normal position without speed or jerking.
Duration
This asana is difficult in the beginning, especially for women with heavy hips and men with big belly’s. Initially you can take help from another person while raising the hips and waist. This asana should be maintained for 2 to 3 minutes after sufficient practice to get the desired results.
Internal Effects
Most of the times we remain either in a standing or sitting position. Quite the opposite position is taken in this asana. This helps improve the blood circulation as impure blood easily reaches the heart. To some extent you can get the benefits of Shirsasana (up side down) in this posture.
Precaution
This asana should not be performed by people who are suffering from heart trouble and blood pressure problems. It can only be practiced under expert guidance.
