When the King Anawrahta marched to China, on the way he saw a Nat sitting on the big branch of Htein tree which was assigned to him to guard by the higher Nat. Getting angry abruptly with the Nat at his arrogant demeanour, King Anawrahta ordered Kyansittha to beat the Nat with his mystic cane stick. Thus Htein tree Nat became so frightened that he ran away, and since then having a grudge against the King Anawrahta, a deep-seated resentment over the way he had been treated, he silently waited for a chance to avenge. Eventually when the King Anawrahta’s fate began to fade away, the Nat guardian of Htein tree in the guise of a wild buffalo killed him in revenge. So legend has it that King Anawrahta met his death in such a way being killed by a wild buffalo.
