I'm considering spending some time in the future in retreats to have a taste of what monastic life is like. It seems that Theravāda is the current tradition most related and compatible to my moral principles and philosophical ideas.
But before spending too money on flight and residence without complete certainty on the differences and traits of schools around the globe, I'd like get enough information.
So, as I've written in the title, what are the main differences between schools, lineages, branches and sects in the Theravāda tradition?
Also, only if possible -and if it's allowed by the forum's rules-, if you were to go forth, what monastery would you choose, and why? (Just in case, I'm not asking what tradition is better or what is the closest one to the original teachings, because every sect can say that they're the ones).
Thanks for your time! Have a nice day!
