大般涅槃経
There are several major Indian texts which discuss the idea of Buddha-nature and they are often termed the tathāgatagarbha sūtras. According to Brunnholzl "the earliest mahayana sutras that are based on and discuss the notion of tathagatagarbha as the buddha potential that is innate in all sentient beings began to appear in written form in the late second and early third century." Their ideas became very influential in East Asian Buddhism and Tibetan Buddhism. Mahayana sutras which mention this doctrine include the "Tathāgatagarbha sūtra", "Anunatva-Apurnatva-Nirdesa," "Śrīmālādevī Siṃhanāda Sūtra," "Mahāyāna Mahāparinirvāṇa Sūtra, Aṅgulimālīya Sūtra" and the "Laṅkāvatāra Sūtra".
