3.39

佛告富樓那彌多羅尼子。富樓那者字也。此云滿江。故福德經云。王舍城內有婆羅門。夫妻二人大富無兒。二人往滿江邊求祠梵天王乞兒。設諸香花并誦神呪。婦夜感夢。夢見有人器盛滿寶物授與其妻。妻即安置腹前。器遂入腹。寤已說夢。其妻父母為解曰。必是梵王與汝兒也。若生當為寶器。遂因有娠。此兒生後聰明。論義第一能伏外道。佛滅度後誦出阿毘曇藏。從江作名故稱為滿江。亦從願作名。依未曾有因緣經云。富樓那以嫉妬心後割愛入山誦九十種經。滿二十一年還王舍城。頭上然火。以銅鐷鐷腹唱云。我是一切智人後佛降之。即說偈云。若多少有聞自大以憍人。如是盲執燭照彼不自明。以智慧故投地未起得阿羅漢果。彌多羅尼子者。彌多羅是母名。外道四圍陀論中有彌多羅品。其母誦此一品。從所誦為名。此云慈行亦云善知識。尼者女也。同名既多。故以母別標之。富樓那辯才第一不達根性故被呵也。無垢經云。滿慈子也。

"The Buddha told Pūrṇamaitrāyaṇīputra:" Pūrṇa is his personal name. Here it is translated as "Full River" (Manjiang). Thus the Fude jing states: In the city of Rājagṛha there was a Brahmin; husband and wife were extremely wealthy but had no children. The two went to the bank of the Pūrṇa River to sacrifice to and pray to Brahmā-rāja, begging for a child. They set out various fragrant flowers and chanted divine dhāraṇīs. At night the wife had a dream: she dreamed she saw a person holding a vessel filled with precious things, which was given to his wife. The wife placed it in front of her belly, and the vessel subsequently entered her belly. Having awoken, she recounted the dream. The wife's parents interpreted it for them, saying: "It must be that Brahmā-rāja is granting you a child. When born, he will surely be a precious vessel." She subsequently became pregnant because of this. After this child was born, he was intelligent, foremost in debate, and able to subdue non-Buddhists. After the Buddha's parinirvāṇa, he recited and chanted forth the Abhidharma Piṭaka. He took his name from the river, and was therefore called "Full River." His name was also taken from a vow. According to the Weicengyou yinyuan jing: Pūrṇa, with a mind of jealousy, later cut off worldly attachments, entered the mountains, and recited ninety kinds of scriptures. Having fulfilled twenty-one years, he returned to Rājagṛha, lit a fire on his head, strapped his belly with copper plates, and proclaimed: "I am an omniscient person!" Later the Buddha subdued him, and immediately spoke a verse: "If one has heard a little and exalts oneself to be arrogant toward others, / it is like a blind man holding a lamp: it illuminates others but does not enlighten himself." Through wisdom, before he even arose from throwing himself to the ground, he attained the fruit of an arhat. "Maitrāyaṇīputra": Maitrāyaṇī is the mother's name. In the non-Buddhist treatises of the four Vedas, there is a "Maitrī Chapter." His mother recited this one chapter, and took her name from what she recited. Here it is translated as "Benevolent Practice" (Cixing), and also as "Good Friend" (Kalyāṇamitra). "-nī" means "woman." Since many shared the same name, he was distinguished by referring to his mother. Pūrṇa was foremost in eloquence, but because he did not comprehend the capacities of beings, he was rebuked. In the Wugou [cheng] jing, he is called Mantcizi.
