In Buddhism, three types of Buddha are recognized. * Sammasambuddha, often simply referred to as Buddha * Paccekabuddha * Savakabuddha The first two types of Buddha both achieve Nirvana through their own efforts, without a teacher to point out the Dharma. The term Savakabuddha does not occur in the Theravadin Pali Canon, but is mentioned in three Theravadin commentarial works, in Mahayana texts like Shantideva's Bodhisattvacharlavadacrechlkyadifaeikyavatara and in the Tibetan tradition, and refers to an enlightened disciple of the Buddha.
