This Asana has come through tradition. Its reference is not found in old Yogic Texts.
Position of Readiness
Stand erect with legs together, hands by the side of the thighs. Make two or two and half feet distance between two legs and raise both the hands towards each side, so to make a parallel line with shoulder.
Now bending lateral towards right side, slowly bring your right hand downward and carry left hand towards the sky.
Slowly bring your right hand upto the right ankle.
Now slowly return to the position of readiness.
Rest for 1 to 2 breath and repeat the same for the left side by bringing your left hand towards left ankle.
This makes one round of Konasana.
Its practice makes the spine flexible. It relives back and buttock pain.
Those suffering from cervical and lumbar spondilitis and hypertension should consult yoga expert before practice it.
