Benzaiten
In the Rig-Veda (6.61.7) Sarasvati killed the three-headed snake, also known as Vritra. This is probably one of the sources of Sarasvati/Benzaiten's close link with snakes and dragons in Japan. She has a shrine on the Island of Enoshima in Sagami Bay, about 50 kilometers south of Tokyo; and a five-headed dragon and her are the main people in the Enoshima Engi, a history of the shrines on Enoshima written by the Japanese Buddhist monk Kokei (皇慶). According to Kokei, Benzaiten is the third daughter of the dragon-king of Munetsuchi (無熱池; literally "lake without heat"), the lake which is at the center of the world in an ancient Buddhist view.
