Yoganidrasana, (Sanskrit: योगनिद्रासन) or Yogic Sleep Pose is a reclining forward-bending asana in modern yoga as exercise. It is sometimes called Supta Garbhasana (Reclining Embryo Pose). The name Dvi Pada Sirsasana is given to the balancing form of the pose. In hatha yoga, the pose was used in Pasini Mudra, the noose mudra, a seal to prevent the escape of prana; it was not an asana.
