Durvasasana or Durvasana, is an advanced standing asana in hatha yoga, with one leg raised and the foot hooked behind the neck. The similar Trivikramasana has the raised leg straight. There are seated and reclining variations including Bhairavasana. Versions of the pose are depicted in statues in Karnataka and Tamil Nadu from the 8th century onwards. Trivikramasana is described in the 18th century Haṭhābhyāsapaddhati; a pose close to Durvasasana is illustrated as "Trivikramasana" in the 19th century Sritattvanidhi.
