Shirshasana from front and side
Shirshasana (Sanskrit: शीर्षासन, IAST: śīrṣāsana) Salamba Shirshasana, or Yoga Headstand is an inverted asana in modern yoga as exercise; it was described as both an asana and a mudra in classical hatha yoga, under different names. It has been called the king of all asanas. Its many variations can be combined into Mandalasana, in which the legs are progressively swept from one variation to the next in a full circle around the body.
