Bahuśrutīya. A subschool of the Mahāsaṃghikas which emerged in the 2nd century bce and flourished mainly in south-east India around Nāgārjunakoṇḍa. A single inscription suggests they were also present in the north-west of India, but this is almost certainly based on a misreading. Little is known about the distinctive doctrines of this school although it is reported that they stressed the profound implicit meaning of sūtras in contrast to their parent Mahāsaṃghika school whom they criticized for not going beyond the superficial explicit meaning. It is known that their canon comprised five elements with the addition of a Saṃyukta Piṭaka and a Bodhisattva Piṭaka alongside the standard three. However, nothing of their literature survives with the exception of the Satyasiddhi Śāstra of Harivarman which has been thought to have a connection with the Bahuśrutīya school.
