It is believed to be the place where Rama quenched the thirst of Sita by dipping the bow into the sea water. There may be some scientific reasons for the existence of pure water spring inside the saline water body, but there is a mythical story which states the existence and the reason for the good water spring inside the sea in this place. After rescuing his wife Sita from Ravana, Rama with his crew flew to Ayodhya by means of pushpaka vimana (A flying machine acquired from Ravana). On the way, the crew asks for water. Rama took his arrow and shot it into the sea, the place where his arrow pierced in the sea, emerged a freshwater spring. The crew then quenched their thirst and thanked, Rama.
