Most of the early sutras that have survived are from Sthavira nikaya schools, no complete collection has survived from the other early branch of Buddhism, the Mahāsāṃghika. However, some individual texts have survived, such as the "Śālistamba Sūtra (rice stalk sūtra)." This "sūtra" contains many parallel passages to the Pali suttas. As noted by N. Ross Reat, this text is in general agreement with the basic doctrines of the early sutras of the Sthavira schools such as dependent origination, the "middle way" between eternalism and annihilationism, the "five aggregates", the "three unwholesome roots", the four noble truths and the noble eightfold path. Another important source for Mahāsāṃghika sutras is the "Mahāvastu" ("Great Event"), which is a collection of various texts compiled into a biography of the Buddha. Within it can be found quotations and whole sutras, such as the Mahāsāṃghika version of the "Dharmacakrapravartana".
