Parvati is the wife of the Hindu god Shiva - the protector and regenerator of universe and all life.She is the daughter of the mountain king Himavan and mother Mena. Parvati is the mother of Hindu deities Ganesha and Kartikeya. Some communities also believe her to be the sister of the god Vishnu and the river-goddess Ganga.
With Shiva, Parvati is a central deity in the Shaiva sect. In Hindu belief, she is the recreative energy and power of Shiva, and she is the cause of a bond that connects all beings and a means of their spiritual release. In Hindu temples dedicated to her and Shiva, she is symbolically represented as the argha or yoni. She is found extensively in ancient Indian literature, and her statues and iconography grace Hindu temples all over South Asia and Southeast Asia.
