I made a visit to a Vietnamese Buddhist Temple today that is about 20 minutes from my home that done "prayers" / chanting on Sundays, a particularly convenient day for me since I don't have to work. While I didn't understand a bit of their chanting (all Vietnamese, no Pali), I was impressed by the devotion expressed by those who were there and am considering returning, if for no other reason than to attend the yoga course offered immediately preceding.
I was a little curious, however, as to any differences anyone here can think of between Theravada and that which is practiced (in general) by Vietnamese monks and nuns. In this particular case, there was a single nun present and, somewhat to my surprise, she ate with everyone at the lunch offered after the service (around 1PM). I guess I'm just curious if there are different Vinaya rules.
I am thinking about posting this question on Dharma Wheel, but I haven't done so yet (since this is sorta my "home" forum).
Thanks in advance for any insights.
