The name comes from the Sanskrit words
Kraunch (क्रौञ्च) meaning "heron", and the name of a mountain.
Asana (आसन, āsana) meaning "posture" or "seat".
The pose is sitting with one knee forwards on the ground and the foot beside the hip, as in Virasana, the other leg straight and raised to touch the nose and chin, the foot grasped by both hands. It provides a stronger forward bend than Paschimottanasana. The posture is stated to be unsuitable during menstruation.
