Tibet’s exiled spiritual leader, the Dalai Lama, begins a visit to Washington D.C. this week, to celebrate his birthday and guide followers of Tibetan Buddhism in a 10-day prayer and meditation ritual.  VOA’s William Ide reports the Dalai Lama’s visit, which is likely to upset China, is his first to the nation's capital since he stepped down as the political leader of the Tibetan government in exile earlier this year.
