佛祖統紀 5.22

5.22

十五祖羅睺羅多尊者。迦毘羅國人。聰慧異常。迦那提婆尊者至迦毘羅國。有長者淨德。園樹生耳如菌。唯長者與子羅睺羅多。取而食之。取已隨生。自餘親屬皆不能見。尊者知其宿因。遂至其家謂之曰。汝家昔曾供養一比丘。以道眼未明虛沾信施故。報為木菌。唯汝與子。精誠供養故得享之。又問長者年多少。曰七十九。尊者說偈曰。入道不通理。覆身還信施。汝年八十一。此樹不生耳。長者歎服。即令其子出家。尊者曰。昔如來記此子。當第二五百年為大教主。即與剃𩬊仰受付囑。大弘正法。有婆羅門造鬼名書十萬偈。甚為難解。龍樹一聞便曉。提婆再聞亦曉。羅睺聞提婆說亦得解了。婆羅門大驚曰。沙門似若舊習。遂即信服。羅睺化緣已畢遂取涅槃。眾收舍利起塔供養（付法藏經）。

The fifteenth patriarch, the Venerable Rāhulata, was a man of the country of Kapila, extraordinarily intelligent. When the Venerable Kāṇadeva arrived in the country of Kapila, there was an elder named Śuddhapunyodaya, in whose garden a tree grew fungus like mushrooms. Only the elder and his son Rāhulata gathered and ate them; as soon as they were gathered, they grew back again, while the rest of their relatives could not even see them. The Venerable One, knowing the past cause, went to his house and said to him: 'In the past your family made offerings to a monk; because the eye of his Way was not yet clear, he vainly partook of the offerings of the faithful, and was retributed as a tree mushroom. Only you and your son made offerings with pure sincerity, so you are able to enjoy them.' He also asked how old the elder was. He said: 'Seventy-nine.' The Venerable One spoke a verse: 'Entering the Way without comprehending the principle, / One covers one's body to repay the offerings of the faithful. / When you reach the age of eighty-one, / This tree will no longer produce mushrooms.' The elder sighed in admiration and straightway had his son leave household life. The Venerable One said: 'Formerly the Tathāgata prophesied that this boy would become a great master of the teaching in the second five-hundred-year period.' He then shaved his hair and respectfully transmitted the entrustment to him, greatly propagating the true Dharma. There was a brāhmaṇa who composed a book of ghost names in one hundred thousand verses, which was exceedingly difficult to understand. Nāgārjuna understood it upon hearing it once; Deva understood it upon hearing it twice; Rāhula also came to understand it upon hearing Deva's explanation. The brāhmaṇa was greatly astonished, saying: 'The śramaṇas seem as if they had practiced it of old!' and straightway had faith and submitted. His teaching affinities completed, Rāhula entered nirvāṇa. The assembly gathered his relics and erected a stupa to make offerings. (From the *Fu fazang jing*.)
