This asana is beneficial for the digestive and reproductive systems. It stretches the stomach and intestines, all alleviating constipation. The backward bend loosens up the vertebrae and stimulates the spinal nerves, relieving backache, lumbago, rounded back and drooping shoulders. The front of the neck is fully stretched, toning the organs on this region and regulating the thyroid gland.It gives energy to the chest and the lungs, and checks tridosha
Physical- on the abdomen, throat, spine or natural breathing.
Spiritual- on swadhisthana or vishuddhi chakra.
It is important that this asana is followed by any forward bending asana, such as paschimottanasana, to release any tension in the back. The most convenient counter pose is shashankasana since it may be performed immediately from vajrasana without unnecessary body movement.
Contra-indications: People with severe back ailments such as lumbago should not attempt this asana without expert guidance. Those suffering from enlarged Thyroid should also take care.
