高僧傳 9.19

9.19

後郭黑略將兵征長安北山羌，墮羌伏中。時澄在堂上坐。弟子法常在側。澄慘然改容曰：「郭公今厄。」唱云：「眾僧呪願。」澄又自呪願。須臾更曰：「若東南出者活，餘向則困。」復更呪願。有頃曰：「脫矣。」後月餘日，黑略還，自說墮羌圍中，東南走馬之際，正遇帳下人推馬與之，曰：「公乘此馬，小人乘公馬，濟與不濟，任命也。」略得其馬，故獲免。推檢日時，正是澄呪願時也。

Later, Guo Heilüe led troops to campaign against the Qiang of the northern mountains of Chang'an and fell into an ambush by the Qiang. At that time, Deng was seated in the hall, with his disciple Fachang by his side. Deng looked sorrowful, changed countenance, and said: "Lord Guo is in distress now." He called out: "Let the assembly of monks make vows!" Deng himself also made vows. After a brief moment, he said again: "If he exits toward the southeast, he will survive; in other directions, he will be trapped." He made vows again. After a short while, he said: "He has escaped." More than a month later, Heilüe returned and recounted how he had fallen into the Qiang encirclement; while galloping on horseback toward the southeast, he happened to meet one of his attendants who pushed a horse toward him, saying: "My lord, ride this horse, and I will ride yours; whether we make it or not is up to fate." Heilüe obtained his horse and thus managed to escape. When they verified the day and hour, it was the exact time Deng had been making vows.
