The Sarvanga Asana is one of the most treasured asanas, said to benefit the whole body. In this asana the whole body weight rests on the shoulders and the neck and upper back regions are stretched to the limit. Beginners should practice the sarvanga asana in a moderate way and gradually attempt the full posture.
The Sanskrit word sarvaanga means limb or body. sarvanga therefore translates as either "all-limb" or "whole-body posture". It is so named because of the benefit it provides to the entire body. It is commonly referred to as the "shoulder-stand" because one is essentially standing on one's shoulders.
The sarvanga-asana is considered by many to be the most beneficial of all yoga postures. Because of its many benefits, if you find that your time is limited in the course of Yoga practice at home, it is recommended to place special emphasis on the sarvanga-asana.
