By Swami Harshananda
Mudrās are yogic exercises described in works on Haṭhayoga, like the Gheranda Samhitā. They are said to help in controlling the involuntary muscular and nervous systems.
Bhujaṅginī-mudrā is the last of the 25 mudrās described in the Gheranda Samhitā. It performed by extending the neck a little forward and drinking the air through the mouth by opening and expanding it a little. All the disorders of the stomach, especially indigestion, are expected to be cured by this mudrā.
