You think tamilnadu was part of mughal rule? Was it part of ashoka's rule? Was it part of any rule except for last 100 or so years? Tibetans since their begiining could not choose their own Dalai Lama. They had to go before their chinese emperor with a list of names. The chinese emperor chose their dalai lama for them :D. Tibet was always a surrogate kingdom under chinese emperor's hold. Just like say a smaller kingdoms in india existed under Ashoka's rule. They accepted Ashoka as the emperor and were 'allowed' to rule by themselves. Dont talk without knowing history.
