In Sanskrit, the firefly yoga pose is known as Tittibhasana. The word "Tittibhasana" derives from two Sanskrit words, the word " Ṭiṭṭibha" denotes "small insect or firefly", and the word " asana" means "posture" or "seat".
The firefly yoga pose is an arm balancing yoga pose, in which your legs are stretched out forward. The variations of this pose are Bhujapidasana, with the legs crossed at the ankle, and Eka Hasta Bhujasana, with one leg, stretched out forwards.
