‘Sarvanga’ refers to ‘whole’ or ‘everything’, as well as the benefits yielded by this posture to all parts of the body. Which, is also known as Salamba Sarvangasana or the shoulder stand, specially works on the throat energy centre (Visuddha chakra), increases blood supply and nourishes the brain. As Salamba Sarvangasana, this is a basic posture to all beginners.
For Beginner , i suggest you to partice this posture against the wall to prevent your neck injuire. First, lie on your side with your knees drawn up, placing your shoulder and hip along the edge of your matwith your buttocks touching the wall, roll over on to your back and levelling your buttocks against the wall, keep your spine straight and step your feet up the wall with your knees bent so press your elbows down into the floor and place your palms on your back.To follow by Halasana (the plough) and Matsyasana (fish posture) will enhance the effect and provides a complete counter-stretch to Sarvangasana, so I strongly require all practitioners to finish these three postures as a set.
It is the queen of all posture due to its good effect at balancing Hormones, maintain of circulatory and endocrine systems, ensuring the regeneration of cells, bones and bodily engergy. This posture is good for those people with asthma or cough badly. However, people with high blood pressure have to pay extra attention when practising this posture, I suggest to start with Halasana and hold for 3 minutes, then you can try Sarvangasana.
