本文嘗試深入解析宋真宗大中祥符九年（1016）所發生的智悟「斷臂祈雨」事件，以及智悟回鄉後卻成為魚肉鄉里的「妖僧」的原因。整文大致分成四個部分來討論，（1）斷臂的原因，可能與佛教《法華經》傳入中國後所帶來的「捨身」精神有關，並由隋、唐一路延續而來。（2）由於唐代以後禪宗的大盛，導致僧人對於教義的追求日趨減弱，再受到現實環境的影響之下，僧人甚至成為巫術的施行者。（3）由於記載此事的《佛祖統紀》與〈尚書工部郎中歐陽公墓誌銘〉對智悟的描述可謂天差地遠，因此從文本來分析，進而得知這可能是出於兩位作者書寫理念的差異所導致。

This article attempts to analyze deeply about the episode of ＂Broken arm, praying for rain ＂, which occurred in the 9th year of Song Zhenzong(宋真宗)DazhongXiangfu(大中祥符)(1016), and the reason why Zhiwu(智悟)became a ＂bad monk＂ after returning home. The whole article is roughly divided into three parts. (1)Thecause of the broken arm may be related to the idea of sacrificebrought by＂法華經＂, and has been gone on since the Sui Dynasty and the Tang Dynasty. (2)Due to the great prosperity of the Zen(禪宗) after the Tang Dynasty, the monks were weak to pursuit the doctrines of Buddhism, and under the influence of the reality, the monks even became the practicer of witchcraft. (3)Thedescription of Zhiwu(智悟)in ＂佛祖統紀＂ and ＂尚書工部郎中歐陽公墓誌銘＂ is very different. Therefore,the difference idea of two writers can be realizedby analyzing the context.
