[5] The pose is illustrated in half-tone in the 1905 Yogasopana Purvacatuska and named Dhanurāsana, quoting the Gheranda Samhita's description.[6] It is unclear whether the asana is medieval, as although the name is used, the intended pose might be the sitting Akarna Dhanurasana rather than this backbend.The account of Dhanurasana in the 15th century Hatha Yoga Pradipika is ambiguous about whether the pose is reclining or sitting, stating[1] Having held the big toes of both feet with both hands, one should pull [them] like a bow as far as the ears.(HYP 1.25)The 17th century Gheranda Samhita is similarly ambiguous, stating Spreading the legs on the ground, straight like a stick, and catching hold of the feet with the hands, and making the body bent like a bow, is called by the Yogis the Dhanurasana or Bow-posture.[8] From a prone position, the feet are grasped to lift the legs and chest to form the shape of a bow with the body, with the arms representing the bowstring.
