釋鑑稽古略續集 1.91

1.91

帝問揀壇主云。何處有佛。揀奏云。我皇即是佛。帝云。朕如何是佛。揀云。殺活在於手。乾坤掌上平　帝年八十歲乃云。與釋迦如來同壽不為天矣　帝崩。靈駕經宣德。現大圓光周遍天界合境。僧俗悉皆瞻禮。蓋顯古佛示現之作用耳（以上出弘教集具見佛祖通載）。

The Emperor asked the Master of the Altar Jian: "Where is there a Buddha?" Jian memorialized: "My Emperor is precisely the Buddha." The Emperor said: "How am I the Buddha?" Jian said: "Killing and giving life reside in your hand; Heaven and Earth are balanced upon your palm." When the Emperor reached eighty years of age, he said: "Living to the same age as Śākyamuni Tathāgata cannot be deemed dying young." When the Emperor passed away and the spirit carriage passed through Xuande, a great circular radiance appeared, encompassing the celestial realm and the entire region; both clergy and laity beheld and worshipped it. This was surely a manifestation of the functioning of an ancient Buddha's apparition. (The above is from the Hongjiao ji and is fully recorded in the Fozu tongzai).
