 The Theravāda is the only surviving tradition of Buddhism that is not Mahāyāna. But at one time, there were many such traditions: eighteen, according to one influential classification. However, apart from the Theravāda, all of these traditions have died out. There is no generally accepted term to refer collectively to all the Buddhist lineages that held Sainthood as their primary spiritual aspiration. In Mahāyāna texts, these forms of Buddhism are called Hīnayāna, the “lesser vehicle”, a pejorative term. More neutrally, these texts sometimes refer to Buddhists who aspire to Sainthood as Disciples (Skt. Śrāvaka) and their path as the Way of the Disciples (Skt. Śrāvaka-yāna). Some scholars have proposed the term “Mainstream Buddhism.”
