The Gaowang Guanshiyin jing 高王觀世音經 was branded “spurious” by Zhisheng. According to Tokuno, Zhisheng makes this judgement on the basis of the text’s known authorship and its annotation, which features a detailed account of the text’s origin. Zhisheng writes that the author of this text was a soldier by the name of Sun Jingde 孫敬德, who was sentenced to death for “petty theft” during the Northern Wei period. The night before his execution, he had a vision of a monk who taught him to recite the Jiu sheng Guanshiyin jing 救生觀世音經. The monk told Sun that the text would shield him from harm if recited one thousand times. The next day, as he was told, Sun recited the text and was protected from the executioner’s blows. Once the chief minister heard of this event, he exonerated Sun and the text was “circulated throughout the world.”
