大唐西域記 9.27

9.27

比丘證果東石崖上，有石窣堵波，習定比丘投崖證果之處。昔在佛世，有一比丘，宴坐山林，修證果定，精勤已久，不得果證，晝夜繼念，無忘靜定。如來知其根機將發也，遂往彼而成之，自竹林園至山崖下，彈指而召，佇立以待。此比丘遙覩聖眾，身意勇悅，投崖而下，猶其淨心，敬信佛語，未至于地，已獲果證。世尊告曰：「宜知是時。」即昇虛空，示現神變。用彰淨信，故斯封記。

At this time the Bhikshu, seeing from a distance the holy congregation, his heart and body ravished with joy, he cast himself down from the mountain. But by his purity of heart and respectful faith for Buddha's teaching before he reached the ground he gained the fruit of Arhatship. The Lord of the World then spoke and said, "You ought to know the opportunity." Immediately he ascended into the air and exhibited spiritual transformation. To show his pure faith they have raised this memorial.

There was formerly a Bhikshu who diligently exerted himself in mind and body, and secluded himself in the practice of Samādhi. Years and months elapsed, and he had not obtained the holy fruit. Retiring from the spot, he upbraided himself, and then he added with a sigh, "I despair of obtaining the fruit of Arhatship (freedom from learning). What use to keep this body, the source of impediment from its very character." Having spoken thus, he mounted on this stone and gashed his throat. Forthwith he reached the fruit of an Arhat, and ascended into the air and exhibited spiritual changes; finally, his body was consumed by fire, and he reached Nirvâna. Because of his noble resolution they have built (this stûpa) as a memorial. To the east of this place, above a rocky crag, there is a stone stûpa. This is the place where a Bhikshu practising Samâdhi threw himself down and obtained the fruit. Formerly, when Buddha was alive, there was a Bhikshu who sat quietly in a mountain wild, practising the mode of Samâdhi leading to Arhatship. For a long time he had exercised the utmost zeal without result. Night and day he restrained his thoughts, nor ever gave up his quiet-composure. Tathâgata, knowing that his senses were fit for the acquirement (of emancipation), went to the place for the purpose of converting him (perfecting him). In a moment he transported himself from the garden of bamboos (Venuvana) to this mountain-side, and there calling him, stood standing awaiting him.
