I learned recently while doing research for #mythmonday that in the etymology for Ṭiṭṭibhāsana, Ṭiṭṭibha actually means “small insect” and has nothing to do with a firefly other than that it happens to be a small insect, and is the one the yoga world chose (I’m guessing because they are pretty.) In fact this asana could very well be called “gnat pose!”
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.
According to the Ashtanga Yoga website: “The story is often used as a symbol of yoga. The sea with its might and power represents the power of illusion, ignorance and prejudice or the general Chitta (चित्त, Citta), i.e. all aspects of human existence subject to change. The small Tittibha (टिट्टिभ, Ṭiṭṭibha)-bird stands for the effort of the yogi, an effort which seems ineffectual when compared with the challenge. But just as the little Tittibha (टिट्टिभ, Ṭiṭṭibha)-bird succeeds in spite of seeming superiority, the yogi can calm Chitta (चित्त, Citta) through practice and shatter illusion.”
