大般涅槃経
Possibly the earliest of these is the "Tathāgatagarbha Sūtra." Other texts in this genre include the "Śrīmālā Sūtra", the "Aṅgulimālīya Sūtra," the "Anunatva-Apurnatva-Nirdesa" and the "Mahāyāna Mahāparinirvāṇa Sūtra" (not to be confused with the Pāli "Mahaparinibbana Sutta" and its parallels).
