• T 418, the Banzhou sanmei jing in three fascicles, is attributed to Lokakṣema 支婁迦讖. Harrison has undertaken a detailed analysis of the two surviving recensions of this text and concludes that it was originally a work of Lokakṣema. One redaction, which survives in the Korean canon and was the basis for the Taishō text, can be considered closer to the 'original,' while the redaction preserved in the Song, Yuan, and Ming canons has undergone modification by a later hand.
• T 419, the Babei pusa jing 拔陂菩薩經 in one fascicle, is an early translation—probably later Han—whose authorship is unknown. This text corresponds roughly with the first four sections (品) of T.418 and the first six chapters of the Tibetan text.
• T 417, the Banzhou sanmei jing 般舟三昧經 one fascicle, is also attributed to Lokakṣema. According to Harrison, this redaction is 'undoubtedly an anonymous abridgement of [the Song, Yuan, and Ming redaction of T.418] into which a long versified passage has been interpolated' (1978: 41). The terminology of the text indicates that it was compiled around the time of Dharmarakṣa (ca. 300) or thereafter. This text was accorded a high place in the transmission of the sutra throughout China and Japan.
• T 416, the Dafangdeng dajijing xianhufen 大方等大集經賢護分 in five fascicles, was translated by Jñānagupta 闍那崛多 et al. in the years 594-595.
