Literally, "the path of the Elders." Of the three major branches of Buddhism, this was the earliest to crystallize into form. In contrast to
Mahayana and
Vajrayana , Theravada emphasizes the individual over the group, holding that it is the individual who must reach nirvana on their own. Its central virtue is thus wisdom, which is to be achieved by the
arhat who attains
enlightenment in this life and
nirvana upon death. It discourages speculation about the nature of the cosmos, enlightenment, and nirvana, instead focusing on meditation to achieve enlightenment. The main social group is therefore the
sangha , the gathered monks and nuns who support and teach each other as each one strives to achieve enlightenment.
