The Laṅkāvatārasūtra is a Mahāyāna Buddhist sūtra classified under the Sūtrānta category. It is one of the nine sacred texts of Nepalese Buddhism and consists of ten chapters with approximately 36,000 verses. The sūtra presents a philosophical dialogue between the Buddha and Rāvaṇa in the first chapter, followed by an extended discussion with Mahāmati in chapters two through ten. It is available in Tibetan and three Chinese translations (NCC). The manuscript in question is a fragment, preserved only up to the middle of the second chapter. Each folio bears the inscription sūtrā laṃkā in the corner, and the final folio contains the colophon: iti śrī sūtrā laṃkāratikā mahāyāna bhagavaṃtaṇ sampūrṇa samāptam (Matsunami). Additionally, there appears to be a gap in the text, possibly meant for an illustration on folio 1b.
