The Diamond Sūtra is a Mahāyāna sūtra from the Prajñāpāramitā, or "Perfection of Wisdom" genre, and emphasizes the practice of non-abiding and non-attachment. The full Sanskrit title of this text is the Vajracchedikā Prajñāpāramitā Sūtra.
A copy of the Chinese version of Diamond Sūtra, found among the Dunhuang manuscripts in the early 20th century by Aurel Stein, was dated back to May 11, 868. It is, in the words of the British Library, "the earliest complete survival of a dated printed book."
The full history of the text remains unknown, but Japanese scholars generally consider the Diamond Sūtra to be from a very early date in the development of Prajñāpāramitā literature. Some western scholars also believe that the Aṣṭasāhasrikā Prajñāpāramitā Sūtra was adapted from the earlier Vajracchedikā Prajñāpāramitā Sūtra. Early western scholarship on the Diamond Sūtra is summarized by Müller.
The first translation of the Diamond Sūtra into Chinese is thought to have been made in 401 CE by the venerated and prolific translator Kumārajīva. Kumārajīva's translation style is distinctive, possessing a flowing smoothness that reflects his prioritization on conveying the meaning as opposed to precise literal rendering. The Kumārajīva translation has been particularly highly regarded over the centuries, and it is this version that appears on the 868 CE Dunhuang scroll. In addition to the Kumārajīva translation, a number of later translations exist. The Diamond Sūtra was again translated from Sanskrit into Chinese by Bodhiruci in 509 CE, Paramārtha in 558 CE, Xuanzang in 648 CE, and Yijing in 703 CE.
The Chinese Buddhist monk Xuanzang visited a Mahāsāṃghika-Lokottaravāda monastery at Bamiyan, Afghanistan, in the 7th century CE. Using Xuanzang's travel accounts, modern archaeologists have identified the site of this monastery. Birchbark manuscript fragments of several Mahāyāna sūtras have been discovered at the site, including the Vajracchedikā Prajñāpāramitā Sūtra (MS 2385), and these are now part of the Schøyen Collection. This manuscript was written in the Sanskrit language, and written in an ornate form of the Gupta script. This same Sanskrit manuscript also contains the Medicine Buddha Sūtra (Bhaiṣajyaguruvaiḍūryaprabhārāja Sūtra).
The Diamond Sūtra gave rise to a culture of artwork, sūtra veneration, and commentaries in East Asian Buddhism. By the end of the Tang Dynasty (907) in China there were over 800 commentaries written on it. One of the best known commentaries is the Exegesis on the Diamond Sutra by Hui Neng, the Sixth Patriarch of the Chan School.
