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 found among the Dunhuang manuscripts in 1900 by Daoist monk Wang Yuanlu and sold to Aurel Stein in 1907.
