it depends on how it is setup.
Bhavana Society is one of the few places that survives without a heavy base of Asian support, and that is due to us being a retreat center as well. We of course have people bring Dana and such as well, which helps, but if we stopped having retreats, we’d be gone in under a year. we are supported almost wholey by monetary donations from retreatants.
I Think Westerners can understand Dana pretty well, but for them it is much more common to have a money donation then to bring food etc. That being said I think more westerners are getting into the whole practice, and I see them more and more engaged in Dana, of food, money, time, and effort.
I have been to some other places with western monks in the West, specifically Thai Forest, who are heavily supported by the Thai community(also not retreat centers), and lets face it, even the western monks are essentially Thai, I don’t even know If I can consider it a “western Theravada Monastery” because it imports the culture as much as the dhamma, same with many Sri Lankan and Burmese places.
That is not to say there is no benefit from the culture and practices, as an anthropology major, I enjoy engaging with the various Buddhist cultures and learning their ways, but I honestly have no desire to become a Sri Lankan,Thai,Burmese monastic, and I am thankfully in a place that allows me to be unaffiliated in this way. You could say that technically I am a “sri lankan monk” as I was called when visiting a Thai place, because of the ordination lineage, but thankfully this is not how my preceptor, or I, see it. The Monks here like to be known simply as monks who follow the Dhamma & Vinaya, and I can get behind that as well, but there is a soft spot in me that wants to see the Dhamma flourish in my country.
I am heavily interested in the creation of an actual American Theravada, not in any official group sense, but in the way I heard put years ago, from a monastic source I no longer remember,but it went something like this " Buddhism has not truly taken root in a country until there are local monastics being supported by local people at local monasteries."
I think Buddhism in America is very young, especially Theravada, and it will be some time until that quote is realized, but I am happy to be in a place that is as close to that quote as you can find here.
