Ganga is a critical figure in mythology because she is the personification of the river Ganga. The river Ganga is important because it is a life-giving and incredibly important source of water for a significant half of the country. It is also one of the most important religious and sacred rivers in India. It is a critical part of the funerary rituals of many Hindus as the goddess is supposed to flow through the three realms and help carry the ashes of the dead to the heavens.
