In terms of geographic expanse, the most widespread is Christianity, featuring four major branches: Catholicism in the west, Orthodoxy in the middle and north, Miaphysitism in the south and Nestorianism in the east. The second most widespread faith in Buddhism, with Mahayana in India, Tarim Basin and Manchuria, Theravada in Sri Lanka and Burma and Vajrayana in Tibet.
