Anoma River

The Anoma is a river in southern Nepal, near Kapilavastu, where Prince Siddhartha renounced the world before becoming Gautama Buddha by cutting off his hair, abandoning his royal dress and exchanging it for the robes of an ascetic. Chinese pilgrims have also recorded the position and the importance of the Anoma river in Nepal.
