One of the early Buddhist schools, the Mahāsāṃghika-Lokottaravāda, were known to be prominent in the area of Bamiyan. The Chinese Buddhist monk Xuanzang visited a Lokottaravāda monastery in the 7th century CE, at Bamiyan, Afghanistan, and this monastery site has since been rediscovered by archaeologists. Birchbark and palm leaf manuscripts of texts in this monastery's collection, including Mahāyāna sūtras, have been discovered at the site, and these are now located in the Schøyen Collection. Some manuscripts are in the Gāndhārī language and Kharoṣṭhī script, while others are in Sanskrit and written in forms of the Gupta script. Manuscripts and fragments that have survived from this monastery's collection include well-known Buddhist texts such as the "Mahāparinirvāṇa Sūtra" (from the "Āgamas"), the "Diamond Sūtra" ("Vajracchedikā Prajñāpāramitā"), the "Medicine Buddha Sūtra", and the "Śrīmālādevī Siṃhanāda Sūtra".
