Diamond Sutra
A vast body of Mahayana Buddhist scriptures of anonymous, collective authorship, composed over several centuries — roughly between the first century BC and the fifth century AD — in India, forming the foundational canonical corpus of 'Great Vehicle' Buddhism, the branch now predominant in Tibet, China, Korea, Japan and Vietnam, in contrast to the Theravada Buddhism of Southeast Asia. These sutras often present themselves as direct teachings of the Buddha transmitted secretly for centuries until humanity was ready to receive them — a literary convention modern scholars interpret as Mahayana's own way of claiming doctrinal authority for theological innovations arising after the Buddha's historical lifetime. Among the most influential are the Heart Sutra and the Diamond Sutra, brief but philosophically extraordinarily dense texts centred on the doctrine of emptiness (shunyata) — all phenomena lack independent, substantial existence, including Buddhist concepts themselves — expressed in the famous formula 'form is emptiness, emptiness is form'; the Lotus Sutra, with its doctrine of the one vehicle and universal buddhahood; the Pure Land Sutra, which describes Amitabha's western paradise and underlies all the Pure Land Buddhist devotion so popular in East Asia; and the Avatamsaka Sutra, of overwhelming cosmic scale, describing a universe of interpenetrating worlds infinitely reflecting one another like Indra's net. Together, these texts shifted Buddhist emphasis from the individual liberation of the arhat toward the ideal of the bodhisattva, who postpones their own final enlightenment to save all sentient beings.
