Buddhism [SEP] Schools and traditions
Buddhists generally classify themselves as either Theravāda or Mahāyāna. This classification is also used by some scholars and is the one ordinarily used in the English language. An alternative scheme used by some scholars divides Buddhism into the following three traditions or geographical or cultural areas: Theravāda (or "Southern Buddhism", "South Asian Buddhism"), East Asian Buddhism (or just "Eastern Buddhism") and Indo-Tibetan Buddhism (or "Northern Buddhism"). Some scholars use other schemes. Buddhists themselves have a variety of other schemes. Hinayana (literally "lesser or inferior vehicle") is sometimes used by Mahāyāna followers to name the family of early philosophical schools and traditions from which contemporary Theravāda emerged, but as the Hinayana term is considered derogatory, a variety of other terms are used instead, including: Śrāvakayāna, Nikaya Buddhism, early Buddhist schools, sectarian Buddhism and conservative Buddhism.
