最古の目録『デンカルマ』に録載されたティベット訳『法華経』の原本について

抄録

The oldest extant catalogue of Tibetan Buddhist works, almost all of them being translations, is the dkar chag lDan/lHan dkar ma. In it is registered the Saddharmapuṇḍarīka (SP), one of the most important and well-known Mahāyāna texts. Its size is noted as 3,900 ślokas (stanzas) and 13 bam pos (volumes). Several other texts are also noted as of the same size, that is 3,900 ślokas and 13 bam pos, including the Mahāparinirvāṇa-Mahāsūtra (MPM) and the Sūryagarbha-sūtra (SG). However, the extents of the texts as we now have them are considerably different, especially between the former (SP) and the latter two (MPM and SG)—they have, e.g. in the sDe dge edition, 359, 300 and 308 pages, respectively. Why is this so? In my opinion, this shows that the present SP is not the original but has been enlarged later. If this is correct, what was the original or former (unchanged) text? I surmise that it would have omitted the last six chapters, and, probably, the latter half of the eleventh chapter as well, as suggested by the contents of Kumārajīva’s Chinese translation.
