Tibetan tradition holds that the soul of a Buddhist monk is reincarnated after death. Now that the Dalai Lama is about to turn 90—this Sunday— Tibetans are anxious to know who will replace him., charged with supporting the nation in exile. The 14th spiritual and political leader of Tibetan Buddhism turns 14 on July 6, and is expected to announce his reincarnation during his birthday ceremony. The announcement has generated excitement, not only among followers of his religion, but also in interested countries: the United States, India, and, above all, China.
