There's a good comment on the article "Will the Karmapa save Dorje Shugden" from a reader called Margaret :
good theory.
I think it will be hard for anyone to have the same influence as the Dalai Lama. maybe that is a good thing though. There needs to be a drastic shift in power. the tibetans are probably too dependent on the Dalai Lama which becomes very difficult in a religious situation. It’s quite contradictory to the Dharma, which teaches us to be independent and not to rely on worldly powers and people. So maybe replacing the dalai lama is what is needed at this time for the tibetans to progress.
.. which brings up a good point: the other paradox that Tibetans often face is that the spiritual leadership of their community could inadvertently restrict them from pursuing real spiritual practice. In this case, the spiritual leadership of the Dalai Lama and his respective policies and bans (such as against Dorje Shugden) are precisely what hinder people from practicing to the fullest extent. Practitioners are faced with the dilemma: follow the advice of their spiritual teacher, or follow the advice of the Dalai Lama. In many cases, this is not a real choice, but a forced one. Following the advice of the spiritual teacher could mean that outwardly it seems to be not following the Dalai Lama, or considered betrayal, not in support of the Tibetan cause etc. This is clear in the cause of the Dorje Shugden ban, of course. Does one continue the practice because it was given to them by their teachers? Or does one abandon it because to keep the practice is tantamount to betraying the Dalai Lama, and risks getting cut off from all welfare, community support etc.
There becomes a dependence on the spiritual leader (though not necessarily the spiritual teacher) which makes it difficult to develop the independence that is encouraged in the teachings - i.e. to be able to question, to debate and for each individual to pursue a distinctly individual and different path unique to them.
Indeed, having a leader less charismatic and influential than the Dalai Lama (and let's face it, there really aren't many people who could be as influential than the Dalai Lama), could be what is most needed in the Tibetan community now. With less of an influence from the spiritual sphere, then it may be easier for the Tibetans to finally carve a clearer distinction between the secular and spiritual, a much needed remedy to the current Tibetan situation.
