In the 6th century BC, Siddharth, Prince of Kapilvastu, left for enlightenment through the eastern door of Tilaurakot Royal palace, at the mere age of 29. In the east of the durbar, there was Anoma River. He reached the banks of the river, shaved his head and sent back the royal clothing and ornaments with horse Kanthak, and horse rider, Chhana to the palace. At present, that place is called Triveni ghat. Anoma River is also referred to as river Narayani. This also signifies that river Narayani has been a pious site for Buddhist since the ancient period.
