The grim spectacle of young monks, nuns and lay people setting themselves on fire to protest conditions in their homeland is a stark reminder of the gloom and despair that now prevails on the Tibetan Plateau. These acts of self-immolation — at least 36 since March last year — have been staged to protest the increasingly heavy controls that China’s government in Beijing has imposed on Buddhist religious practices. At the end of last month, a self-immolation occurred for the first time in Lhasa, the Tibetan capital, which may be a powerful portent of new turmoil in Tibet.
