The term Nikāya Buddhism was coined by Masatoshi Nagatomifake as a non-derogatory substitute for Hinayana, meaning the early Buddhist schools.[1] Examples of these groups are pre-sectarian Buddhism and the early Buddhist schools. Some scholars exclude pre-sectarian Buddhism when using the term. The term Theravada refers to Buddhist practices based on these early teachings, as preserved in the Pāli Canon.
^Robert Thurman and Masatoshi Nagatomi of Harvard University: "'Nikaya Buddhism' is a coinage of Professor Masatoshi Nagatomi of Harvard University who suggested it to me as a usage for the eighteen schools of Indian Buddhism, to avoid the term 'Hinayana Buddhism,' which is found offensive by some members of the Theravada tradition."Thurman, Robert (1981).
