On Sunday, legislators in Tibet's Parliament in exile will cast a historic vote. They have been asked by the Dalai Lama, the leader of the Tibetan spiritual community — and for many Tibetans, the rightful leader of their nation — to formalize the separation of spiritual and political authority.

The Dalai Lama says this move only ratifies a division of labor that already exists and lays the foundation for the creation of true democracy among his followers. Yet for many Tibetans, the move risks splitting their community and undermining its legitimacy. Even the Chinese government, a hostile and implacable foe of the Dalai Lama, is opposed to the plan, fearing that it will make it even more difficult to quiet the nationalist ambitions of many Tibetans.

The Dalai Lama has headed the Tibetan government in exile since he fled Tibet in 1959 after a failed uprising. After settling in the Indian town of Dharamsala, he has become a global figure, the face of Tibetan Buddhism and that society's struggle for self-determination in the face of Chinese efforts to fully assimilate a sometimes hostile population. While millions of people consider the Dalai Lama to be their rightful leader, the government in Beijing sees him as "a splittist," a supporter of a feudal order and a threat to China's core interests.
