 Nearly every day, Tibetan monks and nuns wearing blood-red robes arrive at this distant outpost after a long trek through a forbidding range of mountains. Drawn by word that a brilliant teacher resides here, they climb a twisting path up a narrow valley to find a freshly built metropolis of Buddhist worship. It is a stunning sight in an otherwise barren setting and a potent symbol of the revival in Tibetan Buddhism under way here.A vast assembly of log cabins, spartan inside and out, covers a pair of steep hillsides. At dusk, crowds of monks and nuns buzz in conversation, their hair shorn and their gazes serene, as they gather for evening prayers outside a ramshackle collection of meeting halls that are connected by a criss-cross of muddy pathways. In just a few years, Serthar has emerged to become one of the largest and most influential centers for the study of Tibetan Buddhism in the world.
