Completed Tittibhasana Pose (The Firefly Pose) - Hathayoga

The name of this pose comes from Sanskrit: Ṭiṭṭibha, "small insect, firefly", and āsana, "posture" or "seat".[2]​ An alternative etymology is from the story of a pair of Tittibha birds that nested by the sea; the ocean swept away their eggs, and the birds complained to Vishnu, asking for the eggs to be returned. The god gave the order, and the sea gave the eggs back. The effectiveness of the small weak birds is said to be used as a symbol of yoga, able to overcome the power of illusion in the world.[3] The pose is described and illustrated in the 19th century Sritattvanidhi as Mālāsana, garland pose; that name is given to a different asana in Light on Yoga.[4] - From Wikipedia
