Natarajasana (Sanskrit: नटराजासन, romanized: Naṭarājāsana), Lord of the Dance Pose or Dancer Pose is a standing, balancing, back-bending asana in modern yoga as exercise. It is derived from a pose in the classical Indian dance form Bharatnatyam, which is depicted in temple statues in the Nataraja Temple, Chidambaram. Nataraja, the "Dancing King", is in turn an aspect of the Hindu God Shiva, depicted in bronze statues from the Chola dynasty. The asana was most likely introduced into modern yoga by Krishnamacharya in the early 20th century, and taken up by his pupils such as B. K. S. Iyengar, who made the pose his signature. Natarajasana is among the yoga poses often used in advertising, denoting desirable qualities such as flexibility and grace.
