45.59

十年。夏旱。上於禁中齋禱甚虔。夜夢神僧馳馬空中口吐雲霧。覺而雨大霔。勅求其像得之相國寺閣第十三尊羅漢。詔迎入內供養。宰相王珪以詩稱賀曰。良弼為霖孤宿望。神僧作霧應精求（東軒筆錄）。

In the tenth year, there was a summer drought. The Emperor fasted and prayed with utmost reverence in the inner palace. In the night he dreamed of a divine monk riding a horse in the sky and spitting clouds and mist from his mouth. When he awoke, heavy rain poured down. An edict ordered that an image of him be sought; it was found in the thirteenth Arhat in the pavilion of Xiàngguó Monastery. An edict was issued to welcome it into the palace for offerings. Prime Minister Wáng Guī presented a poem in congratulation, stating: 'A good minister making rain has long disappointed expectations; / A divine monk creating mist answered sincere prayer.' (Note: Dōngxuān bǐlù).
