Sorry for taking so long to reply to this, but here it is.
I have to admit The Broken Buddha was an eye-opener for me too. I had mostly been exposed to the purer part of the Buddhism, and I needed this to gain a more balanced perspective. In fact, even the “purer” part of Buddhism is often not as true to the Buddha’s teachings as some of us would like. I am thinking of such things as the proliferation of wrong view, but also the hierarchical structures that have taken the place of the early decentralised and democratic model.
At the same time, I agree with you that the creation of a new form of Buddhism, a Buddhayana, is not the right answer. Every time we create something new, we also create new divisions and new arguments. There is only one authority that has the ability to unite, and that is the word of the Buddha. So what we really need to do is to heed that word. If we did this fully, most of the corruption of Buddhism would vanish.
How do we get more people, especially monastics, to take the word of the Buddha seriously? I think education is the critical issue. Just understanding where to find the word of the Buddha and then reading it should make a massive difference. This is one of the great things about SuttaCentral: it has mainly been established for this purpose.
