Mahāsāṃghika
The Mahāsāṃghika ( Sanskrit "of the Great Sangha", ) was one of the early Buddhist schools. Interest in the origins of the Mahāsāṃghika school lies in the fact that their Vinaya recension appears in several ways to represent an older redaction overall. Many scholars also look to the Mahāsāṃghika branch for the initial development of Mahayana Buddhism.
