[3] The 19th century Sritattvanidhi uses the name Ardha Chandrasana for a different pose, Vrikshasana.[4] Swami Yogesvarananda used the name in his 1970 First Steps to Higher Yoga for a pose similar to Kapotasana, Pigeon.[7][8] However, Iyengar describes the pose with the upper hand resting on the hip.[7] In Sivananda Yoga and its derivative styles such as the Bihar School of Yoga, half moon pose is Anjaneyasana,[12] an asana used in the moon salutation series (Chandra Namaskar).[13] In Bikram Yoga, the name "half moon pose" is given to a two-legged standing side bend,[14] elsewhere called Indudalasana.
