諱允炆。明太祖之孫，懿文太子之長子，即建文帝也。燕王迫金川門，帝將自盡。王鉞曰：先帝升遐時，附一篋，命臨大難時發之。即進一紅篋，封鎖甚嚴。帝碎篋觀之，內有度牒三葉，一云應文，二云應能，三云應賢。並有袈裟，帽鞋，剃刀及白金十錠。帝曰：命也。即令程濟祝髮，改名應文。時楊應能，葉希賢，亦祝髮，各改名易衣，取牒從鬼門逃。暮至神樂觀，明朝向溧陽而去。自是經湖湘入蜀，遊雲南。後還閩，入廣西橫州南門壽佛寺，住十五年。尋寓南寧一蕭寺，落魄過三十九年。時正統五年，年六十四，恩州知事岑瑛，聞之於京師，賜號老佛，迎入西內。途中賦詩曰：流落江湖四十秋，歸來不覺雪盈頭。乾坤有恨家何在，江漢無情水自流。長樂宮中雲影暗，昭陽殿裏雨聲愁。新蒲細柳年年錄，野老吞聲哭未休。後寂於宮中。弘治中，謚恭仁康定景皇帝。見明高僧傳三，續釋氏稽古略三，元明清史略二等。但明高僧傳等，其名作應能，恐誤。

一應文 （1337～？）諱允炆。明太祖朱元璋之孫，後即位，年號建文。於燕王靖難之變時，剃髮並改名應文，逃離京師。經湖湘入蜀，遊雲南，復還閩，入廣西壽佛寺，住十五年。未久，寓居南寧一蕭寺。流落三十九年後，經恩州知事岑瑛奏聞京師，賜號「老佛」，迎入西內，時年六十四。 於途中，應文賦詩云（大五O‧九一一中）：「流落江湖四十秋，歸來不覺雪盈頭，乾坤有恨家何在？江漢無情水自流。長樂宮中雲影暗，昭陽殿裡雨聲愁，新蒲細柳年年綠，野老吞聲哭未休。」大明高僧傳以其名為「應能」，恐係訛誤。〔大明高僧傳卷三、續釋氏稽古略卷三、明史卷四〕p8055
