Muthiyangana Temple Badulla Sri lanka

At the southern end of Badulla stands the Muthiyangana Vihara whose origins date back 5th Century BC. Buddha is believed to have visited Lanka for the third time, on the eighth year following the supreme enlightenment. King Indaka of pre-historic (meaning prior to our recorded history) tribe Deva (one of the three tribes believed have inhabited Lanka, the other tribes being Yakka & Naga) built Muthiyangana stupa at the location where Buddha is believed to have made the sermons. The stupa was developed into a temple complex by a succession of Sinhalese kings commencing from King Devanam Piya Tissa (307-266 BC), The Deer Hunter, the first Sinhalese convert to Buddhism.
Guardian of the Muthiyangana
To the right of the image house is a statue of god Indaka, the guardian deity of Namunukula mountain range & Muthiyanga. Following his death, king Indaka of Naga tribe was elevated to a deity (most possibly, a superior being in another planet in cosmos) by virtue of his meritorious deeds. That is action & reaction. Lovely.
