Ne Muni

Many historians and local traditions say that a Hindu sage named "Ne" established himself at the valley of Kathmandu during prehistoric times and that the word "Nepal" came into existence as the place protected ("pala" in Sanskrit) by the sage "Ne". The etymology of the name Nepal means, "the country looked after by Ne".
He used to perform religious ceremonies at Teku, the confluence of the Bagmati and Bishnumati rivers. He is said by legend to have selected a pious cowherd to be the first of the many kings of the Gopala Dynasty. These rulers are said to have ruled Nepal for over 500 years. He selected Bhuktaman to be the first king in the line of the Gopal (Cowherd) Dynasty. The Gopal dynasty ruled for 621 years. Yakshya Gupta was the last king of this dynasty. However, this mythology can be challenged as no such name as Ne exists in Nepali or other Sanskrit derived languages.
According to Skanda Purana, a rishi called "Ne" or "Nemuni" used to live in Himalaya. In the Pashupati Purana, he is mentioned as a saint and a protector. He is said to have practiced penance at the Bagmati and Kesavati rivers and to have taught his doctrines there too.
