The Mahāsāṃghikas also split into various sub groups. One of these were the Lokottaravādins (Transcendentalists), so called because of their doctrine which saw every action of the Buddha, even mundane ones like eating, as being of a supramundane and transcendental nature. One of the few Mahāsāṃghika texts which survive, the "Mahāvastu", is from this school. Another sub-sect which emerged from the Mahāsāṃghika was called the Caitika. They were concentrated in Andhra Pradesh and in South India. Some scholars such as A.K. Warder hold that many important Mahayana sutras originated among these groups. Another Mahāsāṃghika sect was named Prajñaptivāda. They were known for the doctrine that viewed all conditioned phenomena as being mere concepts (Skt. "prajñapti").
