Asked whether his successor should be from Tibet or from the diaspora community, the spiritual leader said if his death occured while remaining "outside" then logically the next reincarnation should be from outside Tibet to carry forward his works.
Nothing logical about it, except the bit that says if he can't go back then it's pointless trying to find successor in Tibet because one thing the Chinese ain't going to do is cooperate and nobody has the balls to make them.
