A Close Study of Indrabhūti's Jñānasiddhi: Its Indian Origins and Early Transmission within the Indo-Tibetan Doctrine of the Great Seal (mahāmudrā)

为了更好地理解印度藏传佛教的密宗传统，仔细研究早期的著作是至关重要的。Indrabhūti的Jñānasiddhi，作为早期的基础著作之一，大概是从公元8世纪晚期开始的，它不仅标志着瑜伽向Mahāyoga和瑜伽密陀罗的主导地位的过渡时期，而且还强调了Mahāmudrā的概念，这是密宗佛教的一个组成部分。因此，对其内容、语境和文学史进行文献学研究和深入分析是至关重要的。主要的研究目标是梵文原文的完整文本批判版及其藏文翻译，以及其全面注释的英文翻译。这包括迄今未使用的主要证人，这将大大提高对案文的理解。对密切相关但在很大程度上被忽视的经文的调查，例如，所谓的“七悉经”（Grub pa sde bdun）的Phyag chen rGya gźuṅ，构成了该项目的重要组成部分。这项研究不仅有望对密宗佛教的早期发展提供新的见解，特别是到公元16世纪的大印（mahāmudrā），而且还有望为各种Indrabhūtis的鉴定提供重要信息。虽然Jñānasiddhi由于其重要意义，很早就受到学术界的重视，但迄今为止还没有得到充分的研究。

In order to develop a better understanding of the tantric traditions of Indo-Tibetan Buddhism, the careful study of the early writings is of central importance. Indrabhūti’s Jñānasiddhi, as one of those early and fundamental works, presumably from the late 8th century C.E., marks not only the transition period of the predominance of the Yoga- to the Mahāyoga- and Yoginītantras but also emphasizes the concept of Mahāmudrā, an integral part of Tantric Buddhism. Hence, the philological study and in-depth analysis of its contents, context and literary-history is of paramount importance. The primary research objectives are the full text-critical edition of the Sanskrit original and its Tibetan translation, along with a comprehensively annotated English translation thereof. This includes hitherto unused primary witnesses which will considerably improve the understanding of the text. The investigation of closely related yet largely neglected scriptures, such as, e.g., the so-called "Seven Siddhi Texts" (Grub pa sde bdun) of the Phyag chen rGya gźuṅ, constitutes an essential part of the project. The study not only promises new insights into the early development of Tantric Buddhism in general and of the Great Seal (mahāmudrā) in particular up to the 16th century C.E., but is also expected to provide important information for the identification of the various Indrabhūtis. Although the Jñānasiddhi, due to its significance, has received attention in academia already early on, it has so far not been dealt with in due thoroughness.
