Yu Hai, with clear pronunciation and mellow voice, is from Wanping, Hebei. He was born in the eighth year of Zheng De in Ming Dynasty (15 13) and died in the third year of the apocalypse (1623). He believed in Buddhism since he was a child, and began to visit famous temples in the sixth year of Jiajing (1527). He visited Emei and lived in Wutai before moving to Jiuhua Mountain. When the immaculate monk came to Jiuhua, he saw the beautiful mountains and rivers and was suitable for practice, so he hid in a cave next to the star-picking pavilion in Mokongling, the east cliff. He collected codonopsis pilosula, Polygonatum sibiricum and wild fruits in the mountains for many years to satisfy his hunger. Never went out to raise money or accept charity, and lived to 1 10 years old. Three years after the death of the immaculate monk, his face remained the same as before. Monks respectfully called Innocent "Hundred-year-old Gong", and specially put his body in gold and built a temple to worship him, named "Hundred-year-old Temple". In the third year of Chongzhen in Ming Dynasty (1630), the emperor named Innocent as "Bodhisattva" and Kicking Temple as "Centennial Palace". Later, it was burned down and expanded one after another, thus creating the great temple of the "ten-square jungle". Now, the plaque hanging in front of the Centennial Palace "Bless the Centennial Palace and protect the country forever" was inscribed by Li, the great president of Beiyang Government.

An immaculate monk who was unknown before his death became famous after his death. Why is this? This is related to his whole effort to copy a "Dafang Guangfo Huayan Jing". According to the legend of Jiuhuashan monks, the flawless monk lived 126 years old. Before his death, in order to carry forward the Buddhism and pass it on to the next generation, he used slate as a table and stone as a stool in the cave, took blood from his fingers (when he said he cut his tongue), and copied Hua Yan Jing one by one with a brush dipped in blood and gold powder. It took him twenty-eight years, day and night, and finally copied eighty-one volumes of scriptures and put them next to his right leg. Then he wrote an autobiography, put it next to his right leg, blocked the cave door, and passed away silently. Three years later, Emperor Chongzhen of Ming Dynasty saw a bodhisattva in Jiuhua Mountain in his sleep and sent an imperial envoy to Jiuhua Mountain to burn incense. An imperial envoy found the cave on the top of the East Cliff. When I opened it, I saw an elder sitting in the cave like a stranger, with a copy of Blood Sutra beside him. Looking through his autobiography again, I know that he lived to the age of 126. When Emperor Chongzhen heard the reply, he immediately ordered the construction of a temple, named the "Hundred Years Palace for Protecting the Country", which was filled with gold to worship the true body of the immaculate monk and named the immaculate Buddha.

Jiuhua Mountain has another bodhisattva, which is of course the pride of monks. Therefore, since the Ming Dynasty, all the monks in the past dynasties have regarded the true body of the flawless monk and the Blood Sutra as treasures and kept them well. The merits of the immaculate monk's penance have also been praised by all monks.
