After they met Manjusri in person, Hyonmyung became King Sungdeock and he stabilized the throne of Silla Dynasty. Since he believed he was indebted to Manjusri, he built and restored the temple to repay the favor of Manjusri.

Originally, the temple was called Jinyeowon.

He came to Sangwonsa Temple to take a rest. One day, he took a bath at the stream in front of the temple, and he encountered the present of Manjusari.

A little boy helped him to take a bath in the stream. When Sejo told the little boy not to tell anyone that he saw the king. Then, the little boy told Sejo that do not tell anyone that he saw him and disappeared. After the little boy disappeared, he realized that the boy was the present of Manjusri. To memory this miracle incident, King Sejo ordered to make a statue and paint a painting of Munsoodongja (the present of Manjusri).
