Interesting topic at hand here.
It sounds like we are debating a political scheme.
Politics in the world of Buddhism.
But I did not see it mentioned here that all schools of Buddhism are united anyway, as they propitiate, protect and practice the teachings of the Buddha.
The teachings may vary from one interpretation to another and form one person to another.
We just need to look within the same community, be it a monastery or a Dharma center, everybody has differences in its practice, some are given these practices and others given other practices and by the same Guru.
I think it is not the schools and the differences between the schools that are important, what matters is the goal to which the teachings of the various schools of Buddhism lead the practitioners to.
That goal is the same, regardless of the schools, of the colour of the robes.
The boats may have different styles, but they are going towards the same place.
And when that place has been reached, does it matter what colour the boat was?
Yet, when we are on our journey, we can't help but look at other boats and compare and make judgments, this one is bigger, this one has an engine, this one has sails, this one has a buffet 3 times a day, this one, that one, etc...
In reality I cannot know what the Dalai Lama's objectives are, I can infer and use a logic mind to try to understand, with the help of my Guru. But I rely on this: the Dalai Lama knows better than me what must be done.
