仏教論書における引用元の著者表記および引用の形式についての考察――10–11世紀の論書における『修習次第 初篇』の平行句を中心に――

抄録

A parallel passage from the First Bhāvanākrama is found in Chapter 4 of Prajñākaramati’s （ca. 950–1000） Bodhicaryāvatārapañjikā, a commentary on Śāntideva’s （ca. 650–700） Bodhicaryāvatāra, a pragmatic Mahāyāna text. This parallel passage mainly comprises quotations from sūtras, ending with the mention of “Kamalaśīla’s Bhāvanākrama.”

Furthermore, this parallel passage of the First Bhāvanākrama is also found in the *Pāramitāyānabhāvanākramopadeśa, a work attributed to Jñānakīrti （ca. 9c）, and in Atiśa’s （982–1054） Bodhimārgadīpapañjikā. Interestingly, Atiśa attributes this passage not to Kamalaśīla but to Jñānakīrti. In other words, Atiśa attributes this parallel passage, which can be traced back to Kamalaśīla’s First Bhāvanākrama, to Jñānakīrti. This observation has already been made by other scholars.

In this paper, the focus lies on analysis of the above-mentioned cited passages, primarily within the Bodhicaryāvatārapañjikā and the Bodhimārgadīpapañjikā, both originating from the 10th and 11th centuries. By investigating the contextual factors that may have influenced these different attributions, this study aims to clarify quotation practices in Indian Buddhism during this period, thereby contributing to a comprehensive understanding of quotation practices within the broader context of Indian Buddhism.
