Sarvangasanam

Sarvangasana or Shoulderstand, is an inverted asana (pose) in hatha yoga. Considered as the "queen" of asanas, many practitioners consider it to be an especially important and beneficial pose[citation needed]. Its name in Sanskrit literally means "posture of the complete body."
It is performed by first lying on the back with hands under the mid-back, then lifting the legs and lower body so that the weight of the body is supported on the head, neck, upper back and upper arms.The gazing point is towards the toes. The head must not be turned to the side while in this pose.
Advanced practitioners hold this pose for long periods of time - as much as three hours. However, because of the significant amount of weight being placed on the cervical spine and the threat of neck injury, this is not advisable.
The pose is contraindicated for high blood pressure , whiplash, menstruation, thyroid disorders, angina , and spinal weakness caused by conditions such as arthritis or osteoporosis. If you are pregnant, consult a qualified yoga instructor or your physician before attempting this pose. Viparita Karani - the "legs up the wall" pose - is a common modification.
Matsyasana is normally taken after Sarvangasana as a counter pose. Sarvangasana may be used as a counter pose for backbends such as the bridge. Halasana is often taken as a transitional pose to enter and exit Sarvangasana.
