The Sanskrit Dīrghāgama manuscript is a Sarvāstivāda/Mūlasarvāstivāda text containing a collection of ancient canonical Buddhist sūtras, composed in Sanskrit and written on birch bark folios. This collection had been lost for centuries and was rediscovered in the late twentieth century. In this paper, I examine key instances of intertextuality between a new edition of a sūtra from the (Mūla-)Sarvāstivāda Dīrghāgama – the Sanskrit Prasādanīya-sūtra –, the Pali Sampasādanīya-sutta, and Chinese 自歡喜經 (Zì huānxǐ jīng) – the three corresponding versions of this text in the āgama/nikāya collections of the (Mūla-)Sarvāstivāda, Theravāda, and Dharmaguptaka schools. Hence, contradictions among the texts that are not easily explainable will be shown, uncovering apparent confusion among the creators of these texts and hopefully shedding new light on our understanding of these texts.
