Anantasana (; IAST: ), Sleeping Vishnu Pose or Vishnu's Couch Pose, Eternal One's Pose, or Side-Reclining Leg Lift is an asana in modern yoga as exercise.
The name comes from the Sanskrit words anantÃÂ () meaning "without end" or "the infinite one", for the thousand-headed serpent Shesha upon which Vishnu rested at the bottom of the primordial ocean, and ÃÂsana () meaning "posture" or "seat".
A different reclining pose named Anantasana is described and illustrated in the 19th century Sritattvanidhi. The modern pose is described in the 1966 Light on Yoga.
Anantasana is entered from a lying position. The head is supported with one hand, the upper arm on the ground on that side; the other hand and leg are stretched straight up, the fingers grasping the big toe of the raised foot. The supporting arm, body, and lower leg are in a straight line.
ON 26 December 2024, Chethan Kulkarni held Anantasana for a record duration of 30 minutes.
