53.28

宋仁宗。勅迎陳留佛指入內。試以烈火擊以金鎚。了無所損。俄而舍利流出。乃製發願文送還本寺。初是有梵僧來陳留闡教寺。施天竺佛指。瑞光屢發○徽宗。方士盛言。陳留佛指乃海狗骨。詔取驗之火焚鐵捶十餘日。色不變。乃加禮送還。

Emperor Renzong of the Song decreed that the Buddha finger of Chenliu be brought into the palace; they tested it with fierce fire and struck it with a gold hammer, but it suffered no damage whatsoever. Shortly thereafter, relics flowed forth, whereupon he composed a vow text and sent it back to its original monastery. Earlier, an Indian monk had come to the Chanjiao Monastery in Chenliu and presented the Indian Buddha finger, which repeatedly radiated auspicious light. Under Emperor Huizong, occult practitioners insisted that the Buddha finger of Chenliu was merely a seal bone. An imperial edict ordered it to be tested by fire and beaten with iron hammers for more than ten days, but its color remained unchanged; it was then returned with enhanced honors.
