the branch of theravada we all have now comes from the Mahavihara, which as i understand it was not originally the only game in town as far as theravada was concerned. it's just what we have now thanks to an accident of history (or many accidents whatever)
do you think there is a respectable and respectful way to make a different branch of theravada?
how does one go about this? has it already happened in institutionalised theravada? or is it mostly a western lay movement?
actually any and all thoughts on this subject are welcome.
especially from our ordained members who's lives are more closely tied into how the dhamma plays itself out, is there a fear of change in this regard in the sangha that you can see?

Therefore, the minor differences are just that, no need for new branches, schools, or sects (within Theravada).
