As the rhythm accelerates, the boy -seven-year- old Kinzang Norbu-throws himself to the ground, spinning around rapidly on his back. The music from the speakers is not Buddhist chants but rather pop star Shakira's song "Hips Don't Lie" playing from a white Macintosh laptop computer. And when Norbu spins to a stop in a no-hands headstand, his bright orange, knee-length shirt rides up to reveal a temporary tattoo that spells out-in English letters -"B- Boyz." In one spectacular performance, Norbu has displayed the essence of a country that is attempting the impossible: to jump from the Middle Ages to the 21st century without losing its balance.
