Which tradition was inflexible or hypocritical? Just so I don't accidentally recommend them, hehe!
I've visited some excellent Thai Forest Tradition monasteries that are focussed on the basics, and which put very little importance on rites and rituals and ceremonies.
For example, they had no morning or evening chants, just a short ceremony at food time, informal relations between monks, novices, and the Ajahn.
But, I've also visited stiff, inflexible thai forest tradition monasteries, wheRe vinaya and ritual seem to be the only thing they are interested in.
I recommend just travelling widely and visiting lots of places. I guess the tone of a place is set by the ajahn... His attitude towards what's essential and important ... Good luck finding someone good.
You might have more luck in the west, rather than asia?
Hmm, any specifics...? Sayadaw U Teijania has a monastery meditation centre in Yangon, where everyone is pretty chilled and the emphasis is moreon meditation than anything else. He also ordains people.
Best of luck.
