Eka pada koundinyasana B is one of the most challenging arm balancing yoga poses that improves focus, balance, concentration and inner strength.
Some sources state that Koundinya was created by the goddess, Parvati, to provide wine for the gods. Other texts suggest that he was a disciple of Buddha. It is also said that in order to be able to practice this asana, one needs to have the faith of Koundinya in himself and to find the proper balance between ease and effort.
Beginners might want to support one or both legs with a chair, or practice preparatory poses first, such as placing the right inner thigh on top of the arm and trying to straighten the leg. Then they can try to make small kicks with the back leg and, finally, try to lift it up and straighten it as well.
