Diamond Sutra

The Diamond Sūtra (Sanskrit: Vajracchedikā Prajñāpāramitā Sūtra) is a Mahāyāna Buddhist sutra from the genre of Prajñāpāramitā ('perfection of wisdom') sutras. Translated into a variety of languages over a broad geographic range, the Diamond Sūtra is one of the most influential Mahayana sutras in East Asia, and it is particularly prominent within the Chan (or Zen) tradition, along with the Heart Sutra. A copy of the Tang dynasty Diamond Sūtra was discovered among the Dunhuang manuscripts in 1900 by Daoist monk Wang Yuanlu and sold to Aurel Stein in 1907. It dates back to May 11, 868 CE and is broadly considered to be the oldest extant printed book, although other, earlier, printed materials on paper exist that predate this artifact. The book of the Diamond Sūtra is also the first known creative work with an explicit public domain dedication, as its colophon at the end states that it was created "for universal free distribution".
